I want to clarify a number of things not discussed in this video. Not because the information is particularly wrong. But it's somewhat misleading. I'm an engineer, so I'm going to approach this from an engineering perspective. I have been doing research on grow light spectra for a number of years. I have tested just about every bulb I can get my hands on, from super cheap home lighting LEDs, to very high-end LED grow lights. I have access to expensive optical spectrometers that allow me to measure these bulbs. First some background on how LED lightbulbs work. White LEDs use a true blue LED diode (emitting light around 450 nm) with a combination of phosphors. The phosphors absorb the blue light, and re-emit light at longer wavelengths. The color temperature is determined (almost always, except for super specialty bulbs) not by the type of phosphors used. But by the amount of phosphors used. Typical home lighting LED bulbs use 4 or 5 phosphors. Each phosphor emits a different wavelength such that the sum of light appears white to humans. The wavelengths are around 510, 530, 575, 610, and 660 nm. These cover the range from green, yellow, into deep red. The amount of these phosphors combined with some of the LEDs true blue light mixes and produces white. The "Soft White" bulbs typically have more of these phosphors and emit very little blue light, emitting mostly orange and red, with some blue, and a tiny amount of green. The "Cool White" bulbs emit mostly blue with a bit of orange and red, and almost no green. The specific wavelength of the phosphors used is identical in all LED bulbs due to chemical and physical limitations, manufacturing technology momentum, and market forces. It's simply easier to standardize. These phosphors/wavelengths are also based on what our current technology allows. While other phosphors do exist, they are not used outside of research applications due to cost, chemical safety, etc. Arbitrary wavelength phosphors are not possible since it's based on the chemical nature of the phosphor itself. Similarly to how LEDs only come in specific wavelengths. So what is different about "Grow Lights" The short answer is basically nothing. I do want to point out that there are the purple style grow lights that are comprised mostly of blue and red LEDs. These contain very little or no green and yellow wavelengths, as generally these are seen as less useful to plants. This type of grow light uses plain blue and red LEDs without phosphors.The type of grow light this video discusses is "full spectrum" white grow lights. It's generally accepted that full spectrum is better for plants. But there are some caveats I'll discuss below. The "Full Spectrum" grow lights typically only change one thing: the amount of red phosphor relative to the others. That is, they use the same phosphors as above, but they contain a higher proportion of red. They also typically contain fewer phosphors overall, and emit more of the LED's blue light. This offsets some of the red light, so the light doesn't look red to humans. So more blue, more red, and less yellow and green. The electrical efficiency of grow lights is no better or worse than regular LED bulbs. The amount of light output per watt of electricity is generally 140 lumens per watt. Now a note about plants. It's generally accepted that different wavelengths perform different actions in the plant. Long wavelength UV (350-400 nm) can help promote fungus and pest resistance. Blue light helps prevent activating the plants' shade response which makes long and leggy. This makes it more bushy, and reduces inter-nodal length. Generally 5-15% of UV and blue is sufficient, and more has little effect, except to generate heat and use energy (These frequencies are photosynthetically active, but are very chemically inefficient). Green, yellow and orange are photosynthetically active in the same way as red. However, they are generally less important as they are chemically less efficient than red. The one caveat to this is that some people claim green and yellow help produce better tasting and more nutritious plants. I have not done any research on this. Red is where the plant gets most of its energy. Except too much red, or infrared (>700 nm) can stimulate the plant's shade response, making it leggy, and floppy. So now the million dollar question. As an engineer I want to clarify the goal of the grow lights. And I want to be specific. For some people, it might be that they want to grow the most plants in the smallest area. For others, it might be that they want to grow the most plants with the least energy cost. For others, it might be that they want to produce the healthiest, best looking plants regardless of energy or space consumption. -- For me, I have little room. I want to grow plants in a small space with as little electricity as possible. But I don't like the purple color of red/blue lights. For me, a mix of cool white, and warm white LED bulbs is just fine, and will perform just as well as "grow lights". -- For someone who wants to grow plants commercially, healthy plants with as little energy consumption. Red/blue lights is probably the best bet. -- Expensive "grow lights" are for people with lots of money, who just want healthy plants at any cost. I personally believe, after years of empirical testing (both of spectral measurements, and growing plants), that "grow light" is just a keyword that they can put on the label so they can charge 5-10x as much. I have never seen substantial difference in plant quality between fancy and cheap LEDs as long as the plants get sufficient light to begin with. In all cases, the most important factor is how MUCH light the plants get. The sun puts out insane amounts of light. (generally accepted to be 1000 watts/m^2 on a bright day)(this equals about 100000 lumens per m^2). A light bulb will put out *maybe* 1/200 of this if you have it really close to your plants. You'd need about 120 LED bulbs covering each m^2 to equal sunlight intensity. The more impactful change you can make to grow healthy plants indoors is simply add more light.
Great information, thanks! Would love a video or write up on what bulbs you're using. 😀 I have four clear 4' T8 LED tubes listed as 6500K, 24 watts, 3120 lumens per bulb over my shelf and my plants are doing great!
For people who want to grow with household bulbs a little hack is to cut off the plastic diffusers exposing the bare LEDs. This greatly improves light intensity and throws a more downward beam which eliminates the hassle and cost of using reflectors.
If anyone in interested in more information. I made a 2nd video going over tips and tricks to using household led bulbs including cutting off this diffuser. ruclips.net/video/gy69VpdOpJo/видео.html
doing that can expose electronics that are not meant to be exposed. ie can cause electrocution or fire if shorted, the diffuser is also how these bulbs are able to get the light as spread out and generally useful as they are, if you are gonna cut diffusers just use directional bulbs instead and leave them sealed so nothing bad can happen, cause if it can it just tends to happen, its the way shit is, maybe not to or for you but for sure someone you told to do it know this
@@twistedsocal All important points I should've mentioned. Yes, the bare boards on many household LEDs are going to have exposed points with 110 AC and they absolutely will shock you if you're grounded. No different than a live wire. Still, it's a viable way to make something virtually useless actually work rather decently for growing. Perhaps it's not the best idea for anyone who isn't somewhat handy and doesn't understand or respect electricity. A cheap 6 socket bathroom vanity light with ~15 watt LEDs with no diffusers can easily cover a 3.5 foot by 1.5 foot area. Without the diffusers removed you'd have essentially 0 foot by 0 foot coverage, just not enough intensity.
@@harrypeterson9287 my bad wasn't trying to state the obvious but now a day so many people seem to be runner up for the Darwin awards so i felt it prudent to point out that decapping lights will make them a hazard and also make them far less tolerant to high humidity and moisture. I'm sure just by saying that, we prevented at least one house fire and possibly a death by electrocution. or so is the goal,
@@twistedsocal😐 so this guy that sells grow lights via his company basically made this video as a way to show a "budget build" from home LEDs and he takes off the diffusers on his build. ruclips.net/video/XnIzB_8knLU/видео.html He seems to know what he's talking about and I've tried it multiple times over the last few years on different bulbs. Only trouble I ever had was one bulb that started flickering but there's nothing to indicate the flickering was related to the removed defuser. The defuser is just a plastic done, the actual LED is pretty robust, ie outdoor LED lights can get water in them and still work 🤷♂️ You wouldn't be using grow lights in an environment they'd be in much danger of damage if you're not reckless. Do your own research obviously but quick tip is squeezing the diffuser in a vice makes it pop off fairly easy vs trying to cut or saw it off.
I've been researching grow light strips for a project I'm working on. The "grow light strips" I've found are 3 red 1 blue for lettuces, 4 red 1 blue for flowers 5 red 1 blue for fruiting crops such as tomatoes, strawberries.
Hold on you can get household led bulbs with the same Samsung or epistar led chips in those grow lights you mentioned and easily find them at 4k. Then regarding density why don't you talk about when ten 10w bulbs are use together with the domes removed vs a 100w led grow light ?
I grew cactus, snake plants, succulents, etc with a daylight led bulb I popped the cover off of for years. The LED bulbs are super directional without the cover on them!
I have used 6400k LED bulbs to start seedlings for the past 6 years. Before that I used Daylight 6400k CFL lamps, but the arrival of the cheap LED bulbs, together with a good drop in power used, pushed me to try them. My main crop is superhot chillies that require a long growing season, so I sow early in the New Year, so that the weather outside has stabilised to 10c at night, and the plants are ready to move into bigger pots in my little greenhouse. I see no deficiencies in the plants, and they thrive in our living room until it's time to go outside.
My main issue is the cost/benefit. Grow lights are massively over-priced, and I don't think most people, even those who use standard house lights, believe you can get as good of results with those as you can with grow lights; It's just that if you can get good enough results for your needs, the cost becomes a big factor. For example, aquariums can have fairly affordable lighting, at least until you get to basically ANY of the spot lights, which is the lighting I prefer. Those things are like a hundred dollars bare minimum just because they have the "aquarium light" label. Instead, I use cheap GE outdoor 90w flood leds with the caps popped off; These lights have a second lens touching the diodes such that with the diffuser removed, they become spot lights that grow well even at a 3 to 4 foot distance. Of course most of my plants are shade plants, and I get a bit of (very diffused) natural lighting, so that helps. Even if I needed two or three times the amount of cheap lights to equal the more expensive ones for par, it may well be worth it. The more expensive ones are mostly for all the bells and whistles, appearance of both the fixture and light temp, and yes, slightly better plant or coral growth (based on what I've heard at least; they're out of my price range). And don't even get me started on the rest of the aquarium industry...
I have grown tomatoes under LEDs for years in a spare room. I started these Campari plants from store bought tomatoes ten weeks ago. Currently I have 50 green tomatoes growing on 3 plants in 5 gallon (self watering, wicking) buckets filled with soil mix, all sitting on common chrome metal shelving with about 6 LED strip lights ($15 ea., 5,000 lumens, 6000K color). The 3 buckets are connected to a float valve which is fed by a 5 gallon nutrient bucket, filled weekly. I move the lights up as the plants grow and will begin trimming the lower part of the vine, coiling them before they reach the ceiling. By spring the vines will be about 20 feet long. I get enough side lighting to grow greens close by. TIP: Use inexpensive thin silver Mylar "survival blankets" wrapped around the shelves to reflect even more light.
I have grown dense huge buds using 100 watt equivalent with mixed spectrums 3000 and 5000. I grew a plant that it's main cola was a half ounce so these lights work best in closets and best in grow cabinets and grow box's. They must be close for good results.
i can highly recommend the 23 watt 2700k micro spiral CFLs from Sylvania. I've never had too much luck with any household LED. You could try them out and give a review for the folks on a budget. They're the model X28161LV.
Walmart and Amazon have 7 way splitter sockets for about 10 each. Just screw it in the socket like a normal bulb and then screw 7 bulbs into it. Takes up less than a square foot of space. I just bought 3 and I plan on using a mixture of LED's in each one. Also, Temu has good prices for LED lights. I ordered 6 of the supposed 2000 watt folding garage bulbs. They use about 30 watts in reality but are a good source of side lighting and they have 3000k and 6500k versions for about $10 each. I ended up with a $30 price adjustment refund on my order for 6 of them. Some of the larger foldable LED's for about $15 put out 25,000 lux. I'm getting 10k lux with these up close and the lights stay cool to the touch. Connecting 4 foot LED shop-lights are great for seedlings and clones. I also use them as side lighting for the lower branches and they really do a good job. My 12 cubic foot closet it at 40,000 lux and 3600-4000 foot candles from just Led's. None of them cost me over $60. All of my HID lights are sitting in boxes as relics but I may pull them out for the last few weeks of flowering for an extra kick. Apple Betty, Glookies, Wedding Cake, Runtz Muffin, DosiDo #33, Skittlez, Mimosa Evo, Fruity OG Kush and Fat Bastard are the flowers I'm growing and breeding with. Not to forget freakshow is what I've crossed all of the others with. F2 seeds from any of these will grow 75% normal looking weed and 25% will have the freakshow leaf mutation. If you take a mutant and breed it to another mutant with the recessive gene active, all of those seeds will make mutant plants. So F3 seeds will all look like the Freakshow strain. Cross one with a regular strain and you'll have to repeat the entire process to make that cross mutant. Reading the first half of Genetics for Dummies taught me what was going on with my webbed leaf strain. Later found out it's Frisian Ducksfoot strain and we couldn't figure out why only some of the plants had the webbed leaves. Then I read about Mendellan genetics and easy peezy! P.S. I have a Ducksfoot hybrid (with Flo, G-13, Blueberry, Cinderella 99 and Runtz Muffin stabilized) pollinated by Freakshow. I'm at F1 now and all of the seedlings look normal as expected, but f2 something special is on the way with 25% being a freakshow and 25% Ducksfoot and 1 in 16 seedlings having both recessive genes fully expressed. From there I take a Superfreak female and clone it. Sex reverse one for female pollen and all of those resulting seeds will have both mutations expressed and the seeds feminized! The police saw my grow room and the Freakshow male and loved it! They thought that fucked up looking thing was some funny shit. With what I have invested you better believe I don't screw around with lighting and I choose LED's.
I enjoyed video. I use LED full spectrum 32w bulb for seeds & green by GE for my plants at vegetation stage & then they go into the window for flowering! Works great
Hey man! This video has more information in it then most places I've been searching online. Thank you so much! Also, would you mind answering a question? I have 6 led lights, each is a ufo flat surface led light that produces 21,000 lumens at 5000 kelvins. If I have these hanging at 10 ft, evenly spaced in a building that is 1500 sf, could they grow lettuce in 5 ft grow towers? You've got a subscriber!
Hey, Thank you so much for the Sub! so, to answer your question. With the high power output (21000 lumens=150 watts = APX 60-100Umols) The lettuce should grow. I don't think your growth will be anything thing to write home about as far as speed goes. But maybe teamed with the tower garden, I could be wrong. The 10 feet away is what worries me more. At that distance you would be seeing a fraction of the photon density that you would at say 1 to 2 feet away. You will get that 60-100umols at 1-2 feet, but at 10 feet I'd guess you would receive more like 10umols. Which might not be enough for an entire tower. Unless I just misunderstood you and you were saying the lights will be 10 feet from each other, in which case, go for it Elijah! Your Kelvin being 5000k should be just right for leafy greens, so your in good shape there. 👍
@Humble Growth Hydroponics Thank you for taking the time to reply! The towers are 5 ft tall, and the lights are 5 ft from the ground, so the towers are separated from the lights by 5 ft. Would you suggest I bring the lights closer?
@@elijahbrown7038 Since you are lighting an area rather than a single plant, it might be better to keep the light a little further away so that it can distribute even light to all the plants. Still though, I would move it as close as you can while still lighting the entire area. hope that helps :)
@@elijahbrown7038 Man, you’ve got to start wording your phrases so they’re easier to understand. You can’t get a direct answer, which means we can’t either, because your questions are highly ambiguous. It sounds like a question I’d like to know the answer to, but still don’t. Now, I have to ask for myself.
Awesome input. 👌 thanks. I may have to re shoot this one, I'm afraid I wasn't blunt enough in just saying "yes, you can" just wanted to make people aware of the benefits of a full spectrum grow light and what you would be missing with standard leds. Anyway great idea with removing the cover!!! Thanks for the great comment Mike! 🤙
@@humblegrowthjust run a knife along the edge of the dome several times to loosen the cylicon glue and then use the knife as a lever. It's a bit hard, but doable.
Agreed!!! I have had success with both household LED bulbs that were decapped and regular/high output CFL's growing cannabis. You just have to make sure to run several different wavelengths. That being said, nothing made my plants explode with denser buds like a strong 2000W King LED light. You will not be able to get heavy and dense buds with household LED's, but you can grow very decent buds!
My next grow involves the following- I plan on using a total of 8 lights. 8- 4 Footers. One set is adjustable between 3000- 4000- 5000k, also the wattage is adjustable between 55 and 75. The other set which is primarily for vegetative, runs 40 w 6500k. In the middle part of the growing both of the sets will be on. I have faith that this will work well I cannot type down the entirety of this plan here LOL
This works. I've had so many successful grows. Besides the led bulbs, the last grows i used a few huge CFL bulbs on the sides of the plants, both for vegging and for flowering.
@@grandmajane2593 Not 100% about everything to be honest. I have been researching more affordable short term options for growing aquarium plants and having a few fish tanks. The main tank will be perfect in the basement, occupying a nonfunctional gas fireplace. Planning on having the "lucky bamboo" rooted in the tank and having smaller G.E. par 38 fruit and veggie (clearance now for $4.88 ) provide the light when the bamboo grows above the tank and into the chimney
@@lebowskiunderachiever3591 - That sounds so very interesting. I hope it works out well for you. I've been wanting one of those bamboo plants ever since I saw one on the counter at my local Chinese restaurant.
Help! Is 'full spectrum' the same as 5000k? Can a 'full spectrum' bulb actually have a lower Kelvin number? I believe that even a 5000k build can have a narrow spectrum of light - if it is measured with a spectrometer, which I don't have. I am trying to light my painting studio in the best way... not growing plants. The difficulty is that daylight and 5000k may look the same to our human eyes but they will render color very differently. Any suggestions? - confused in Washington.
Hi, I grow mint in outdoor greenhouse. I get sunlight from 6am to 5pm then I run T5 Led 6500k from 5pm to 10pm. You think this setup works for my spearmint or I am just wasting $$ ? Best regards from Honduras My gol is for mint to grow faster
Hey man, you know those Philips first gen CFL lights You mentioned? I just took one out of a lamp in my shop after 20-some years and replaced it with one of those filament LEDs that uses 1/4 the power but is 5x as bright, lol
Shouldn't basically any light without heavy cooling produce a good amount of infrared? I wonder how big the impact of an normal amount of IR diodes vs the IR of the lamp as a whole is in comparison. In my experience plants really love soft diffused light along witha bit IR as the heat gives them a bit of a boost when growing tropical plants in normal household conditions.

Im currently using fecida 65w 600l and they cost 65€ and have full spectrum Red deepred and bleu so they are doing great! It's great it used a minimum of electric and have no heat on thé led and have iron casing and have vent build in!? Amazing i say that we used to use 2000w lights in thé past..
I am just trying to put some new light bulbs into the already light fixture I have so my plants don't take over by my windows. My husband doesn't want the house to become a greenhouse, and I need to sneak more lights in to grow more plants. 😂 So, I was thinking of installing in my basement office.
That color chart is wrong. Plants use green light and need it. The idea that they don't need green light came from a flawed study from the 1970s, which triggered the market to make grow lights with no green or yellow light, which had sub-par performance.
Caution on the 36 watt SANSI grow bulb! Not worth considering. Their own ppfd slide tells us that, despite having 60 degree lenses, you get less than 200 PPFD at 1ft distance. That's horrible even for the wattage, with 63 diodes at that wattage, they sure are overdriving the LED's. The reviews on it are clear too - it will break very quickly. The only thing qualifying it as a "grow light" is its PPFD slide and the following upcharge. The other linked lamps are far better. Also look around for High bay LED, and floodlights. just avoid the bottom tier efficiency ones.
Did they produce plenty of fruit? I've been a little discouraged with my veggies, and flowering but not fruiting with my diy light array. Guess I need more "warm"/red leds possibly.
If I use a growth lightbulb to grow my plants do I need a special light fixture to attach to the lightbulb in order for the growth light to work or could I simply attach the growth light bulb to a regular light fixture that I already have at home?
Simply use what you already have. Any led light emits synthetic photons that stimulate photosynthesis. So, you can use any bulb and light outlet. The important thing to consider is the light frequency (color, or also called light temperature). I made a video all about light color that will hopefully help. :) ruclips.net/video/D3e5_Eg_7To/видео.htmlsi=XYiIWwO1DoYKgRth
Does it work to use spotlight lamps? I have a light fixture in my kitchen that holds 5 spotlight lamp bulbs and they become pretty hot when they have been on for a while. They are warm white with kinda bare fronts so you can see the diods. Does this work or should I invest in a real growlight instead? (I am really new to being a plant mom)
I've had success in the past with cfl's in both 2700k and 6500k, from start to finish, though I didn't grow a large crop. Just what would fit in a 40 gal garbage can. 😁 I am trying to piece together a "very budget minded" set up with led's in 6500k. I'm just looking to start a few plants for outdoors, but being in a northern climate I will need to start them indoors until mid/late May. I don't think I'll be doing any flowering indoors so I'm just focusing on vegging... We'll see what happens later on, but for now I'm not looking to invest much into elaborate systems.
Excellent! Your on the right track, using "Cooler" light during early growth then almost all "warm" light during flowering. Should do the trick if you can get the photon density high enough. It really all depends on what you are growing. Using a 6500k would be a good overall light temperature, 5000k or even 4500k would offer a little more red light. Growing with a 6500k would give you a healthy, leafy, slightly bushy plant. The buds/harvest will likely be less than what you would get with more red light because red wavelengths stimulate photosynthesis more than any other. I would recommend starting with your 6500k then adding, switching, or using color changing bulbs to achieve closer to 2000k-4000k during flowing.
@@humblegrowth ya. I don't plan to flower with 6500k. Idk if I'm going to try flowering any inside the house or not yet. We'll see what happens when we get there... I am looking at possibly getting a ts1000 or similar. I just have to be mindful of the power bill.
Where can I find tube grow lights that are plastic? i purchased a HydroDesign hydroponic system. It came with 4 Sunco light bulbs. Setup of the system, i broke a light bulb in my hand, so I would like to replace them with plastic bulbs. I have another system that came with plastic tube light bulbs.
I have a quick question. I live in a house built in 1958 and there isn't very good natural light. The windows in my bedroom for, instance, are 18in x 30in and there are 3 of them. one on either side of my bed and one in a coved part of my bedroom (my house has an odd roofline). I want to install light panels or something similar to make it look like there are more windows than there are. Will regular LED light panels be ok, or do I need to create my own using specific LED lights? I am a plant lover and really want to have them in every room, but as it stands they are all in or close to the picture windows in my living & dining room. I know this video is over a year old but I am hoping you might still answer. Thank you!!
It still bothers me a bit that all people who want me to buy grow lights are people who sell grow lights. But your explanations about the light spectrum were really interesting.
Glad you found the light spectrum chat interesting. Just to be clear I’m not selling these lights, I linked the lights on Amazon for you to view them if you’re interested. If you buy I make a commission of like $2 - so the value is really for you not for me.
Not mildew, but algae. Mildew thrives in dank, dark places. Algae loves dank light places. Lucky algae is not harmful to you (it's actually healthy if consumed properly) unlike mildew which can turn into mold and become harmful to humans and animals. The main difference being, mildew is a fungus, with spores (eventually grouping together to create mold) the spores are what are dangerous to breath. Algae is a organism, just like us, similar to the single cell organisms that all life originated from. Regardless, you don't want either in your garden, so avoid light on your wet places, and dank warm dark places.
I have a question if i may ask. I posted a video just a few minutes ago asking this question but i will ask here to see if you can shed some light : ) on my inquiry. I have a full spectrum led light. i have both the veg an bloom on 100%. I used an app called Photone and it shows my light temperature is 12,000k. I understand there is a difference between the color spectrum and the color temperature. For a seedling or a plant in Veg, is there any harm to come from running at 12,000k?
i have a question, have those led light i mean a bulb and has all those colors needed to grow, you think i could use each color for each stage of growing my pants
I personally hate the blue/red sheen of the full spectrum ones. I am not a light sensitive person, but these colors just piss me off. So what I've generally done for my houseplants (mostly tropical greens, non-flowering). Is that, I use Airam Superlux LED in combo with Airam Plant lights LED (full spectrum. LED PAR30 835 800lm E27). The Superlux cancels out much of the visible to the eye blue/red sheen from the grow light, as the Superlux has such a powerful lumen and light spread, vs the grow light. Perhaps a bit inconvenient, needing 2 like that, but I rather make that investment and be creative with the decor aspect of how to set it up in a pleasing way. In order to have the plants grow beautifully through the winter months (north of Sweden), while also still being able to enjoy a welcoming and cozy looking indoor environment.
Even better solution are LED reflektor lights like the ones that are used in construction to light up the rooms. They are low watt and extremely bright. Also extremely cheap compared to grow lights
Sounds like a great experiment... Here's what I've been thinking and workshopping; 10 gallon aquarium on the bottom with a log cut in half, doused with spores then filled with dense fog once an hour for 15 min. on the bottom of the lid I put led strip lights that I can adjust the color of. on the top of the lid, plants with their roots in the fog. Thank you so much for the comments!
@@humblegrowth it does work.. I grow mushrooms. Any light source will trigger mushroom pinning. I just haven't tried complete Cycles under regular LED house lights. I'm sure it'll work mushrooms require the blue spectrum of light
I have a pothos and a tradescantia if I leave it near a open window with no direct sunlight will they still do ok in the room. I have them and also have a lot LED bulbs. I just want big plants. Any tips.
MICRO GROWING WEED 2×2 CONFINED SPACE CUTTING OFF PLASTIC COVER LED HOUSE LIGHTS RIGGING TO A 2×2 FT PLYWOOD 8 LIGHT BULB AND THE PLANTS ARE ALSOM ABSOLUTELY LOVELY
Is there a difference between a regular household 60 watt light bulb vs the daylight 60 watt daylight light bulb which brightness is 760 lumens. These are fairly new on the market.
How about cutting the tops off and putting 3 100w equiv. Led bulbs at a ratio to 3-3000k 1- 2700- 2 6000k veg and 4 3000k 1- 6000k and 1-2700k bud cycle and with this ratio you would get a very realistic spectrum and as for photon density. Make it 50 w /ft2. Is that not the optimum amount that is required for a top notch lighting system. Do this and you will have a serious good system only lacking uv/low red spectrum. 75 bulbs in a 5x5 and that will set you up with all the light to have a terrific grow for $300 or less! Throw a 400w hps in the mix at week 4 of bud if ya really want excellent trichome production. You can manufacture a light with a consistent 1500mmols/ on a 5x5 and with Mylar walls you can go 6x6. $300 to light a 6x6 is cheap and you can make smaller but just follow the 50w/ft2. Rule. Hope this helps people see you can use regular led bulbs when mixed in the right proportions. Try it I promise you a successful grow.
I have 4 6500 k led daylight bulbs is that be enough for 2 plants i have wrapped the setup with aluminum foil but seedlings looks to grow very slowly kindly some one will can give advice how much i have need more until flowering stage
It's hard to say, but it seems like there is a lack in photon density. The sun releases photons that have been making their way out of the core, through plasma then travel 8 light seconds to earth and hit plants in the trillions. Photons are the result of colliding atoms in the center of the sun and contain all the energy we get from the sun. The plants have evolved and adapted to need a particular wavelength of photons for photosynthesis. Household led bulbs create photons through electroluminescence which cannot fully replicate the sun's wavelength of light. Full spectrum grow lights use several different frequencies of light to replicate it the best. House hold leds just can't quite do it. Tbh I created this video to encourage people to use full spectrum grow light bulbs instead, but it totally backfired and now everyone wants to know why it isn't working well for them... short answer, photon density in the proper wavelength cannot be achieved with household leds. This is why your plants are growing slowly, they can't fully trigger photosynthesis. Hope that helps... or maybe confuses you more... sorry
Your plants won't flower without the proper wavelength and photon density. This means you will need a lot more bulbs (like 10) at a "warmer" frequency (red light) for flowering. You will likely need several more lights to even trigger photosynthesis to get to flowering. Or you can buy a couple full spectrum grow light bulbs from Amazon and get there for sure. Hope this helps
@@humblegrowth yes I understand I'm also providing them 5-6 hours of sunlight plants growth is slow but it's growing I'm seen every pair of leaves after 4-5 days. But I really can't afford grow lights so hoping it grows in these critical situation actually it is the bcn critical its tough strain
Trust me, if you said it at all, you’re not to White to say it. I see you my brother from another mother😊. You definitely have your sisters subscription and support, with that one line. Well, you also know your stuff.
Ive a buddy who gets 60g out of 1sq ft from 33w house 2700k led and 15w blurple. Its a mini steath cupboard. So they do work better than most pro growers realise. But it just requires very driextes light inna tight space.
tbh I'm no professional, but managed to grow marijuana with a singular 150w white led light (more on the blue light spectrum instead of red) and some periodic sunlight in windowsill it works fine, I'm in the northern hemisphere with a west facing window so i get the afternoon sunlight. covered 3 square foot 70 cm away from canopy of plants
I have two plants under 5000K LED spots that are doing just dandy bringing them back from near death. good for mother plants, but not for growing flowers.
If someone is just using lights to start seedlings a proper grow light setup is a massive waste of money. This year to start my vegetable garden seedlings early I bought a 100w LED 6500k 10,000 Lumen shop light for $35 as the tubes for my T5 aquarium grow lights blew up. Despite only the small wattage increase I've noticed this year stems are much thicker than last year on my tomato seedlings with the T5 grow lights.
OK so if anybody has any extra grow lights around, please let me know just for like 2 plants I’m trying with a regular 800 lm LED lightbulb I’ve been trying in my window seal I’m dedicated, but need some assistance. Let me know n thanks
lol amzn.to/42pAs6j these lights are solid bulb replacers that put out a pleasant color and have a relatively high PPFD. Hope this helps :) Let me know if you ever want to start a channel, this is my 4th, and I help people setup youtube business's with passive income streams based around their passions, as my other business. :) cheers
House hold led bulbs are the way to go, there cheap effective and they last for years, if you say they don't work, you have not tried them, you need to take the plastic dome off and you need to keep them about 12" above the plants, so if you want to cover a 4ft x 1ft you need to use 6 x 13w bulbs
With basic led bulbs growth will seriously blow, period, not enough spectrum available also, you can grow to finish without dedicated red spectrum, I used to grow with just metal halide hid bulbs, very blue, and it just results in denser buds etc, red is optimal but not a must to flower
@@slicktmi you know, watt for watt still isn't gonna be a defining metric here. Watt per watt LED outputs more lumens per watt than any other light source but has some of the worst penetration ability of any lighting source. Also, sticking to a single kelvin color temp only works for LED nothing else is that specific. Sure light bulbs claim to be of a certain kelvin but they have spikes in many more than just the one they claim sooo growing with an hid vs a fluorescent vs a compact fluorescent vs a cheap led vs something grow specific such as a spider farmer or a gavita pro (I don't even know if gavita makes good LED grow lights but their de hid setups are next to none) sooo if your asking if a fluorescent bulb will grow as well as an hid the answer is hell no, same with most led setups, no but at least with the high end LED setups they cover the needed spectrums. Still in my experience, de hid metal halide bulbs mixed with de hps bulbs in a 40 mh 60 hps setup throughout the entire grow will net the most yield and potential sweetness (think potency here if cannabis is your crop) if you leave out the blue side or the mh you will still grow large buds but not as dense nor as potent and will stretch the plant more. I prefer the closer internodal spacing and thicker main stock of a plant so it can support more weight and in turn will fruit more
@@slicktmi also if you are talking kelvin then you are just sticking to perceived color spectrum and typically the more orange/yellow red side of things yields more but, the blue is far superior in early growth pre flower so flower 2700 5k for pre flower just how it works, still led with high enough lumen can cause light bleaching if too close and still fail to penetrate for crap unless you do some serious pruning. But I have seen some led setups yield more than any hid setup I'm sure strain makes a huge difference as does the ability to keep the grow area cooler but I have seen nearly 3lbs per light off of a spider farmer vs 2.5 average off of gavita de hps. Don't have large scale mixed hid knowledge just smaller boutique grows with mixed hid and or using cmh or plasma setups. Never seen plasma used large scale but I could imagine it could do some rad shit since it is the closest thing we have to sun light in doors but the heat is a killer
@Josh Hall so when you say leds have a hard time penetrating are you talking like deep into the canopy or talking about the leaf itself saying that its not penetrating the leaf enough to photosynthesize?
@@slicktmi oh hell no the LED setups available today have killer abilities as far as growing like I said I have seen larger yields from high end (think 1k a light) setups per light than out of literally any other light source to date, I am guessing a large portion of that is the frequency tuned aspect of LED in general, they are very specific and not what could be considered full spectrum but if you add other wavelength LEDs to the array then you can quite literally tune a fixture to a point that just is not even kinda possible with any other tech available today. The catch is, different plants need different spectrum availability and most grow lamps are most definitely designed for growing cannabis since it is the ultimate cash crop (if you can afford the licenses and permits etc or if you don't mind still working grey market lol but you do you) point is if you want the same results with food crops I doubt that you can find fixtures tuned for specific crops so general tuning or cannabis tuning is the option, great if your growing tomatoes. Not so great for many other crops at least not from where I stand. As far as the LED ability to penetrate I simply mean to undergrowth so anything below the top canopy. Secondary canopy or u der growth suffers, granted it always lacks adequate light but at least with other tech there is enough reflected light to allow under growth to be productive and not make it mandatory to lollipop your crops. The way people grow now, veg is such a short deal, think a week to maybe 3 and right on to flower if grown from clone (gotta keep the killer genetics going and why wait for new seedlings when you can have foot tall babies in 7 days with clonex gel and foliar super thrive feeding sooo simple. So fool proof and sooo much time saved. Anyhow scrog or sog are a thing that has far out paced full term veg and low height plants going into flower with single bud sites can majorly benefit from LED where under growth and secondary canopy are not a thing. Ok I have rambled long enough sorry hope I answered you somewhere in here l
For sure, high pressure sodium lighting is great for large scale production. You are absolutely right. But this video is more for people who want to keep there herbs, greens and houseplants alive just using lights they already have. If you watch the video, you see my skepticism as I always recommend using full spectrum grow lights. But the question is can you use household leds and the answer is actually yes.

I want to clarify a number of things not discussed in this video. Not because the information is particularly wrong. But it's somewhat misleading. I'm an engineer, so I'm going to approach this from an engineering perspective. I have been doing research on grow light spectra for a number of years. I have tested just about every bulb I can get my hands on, from super cheap home lighting LEDs, to very high-end LED grow lights. I have access to expensive optical spectrometers that allow me to measure these bulbs.
First some background on how LED lightbulbs work. White LEDs use a true blue LED diode (emitting light around 450 nm) with a combination of phosphors. The phosphors absorb the blue light, and re-emit light at longer wavelengths. The color temperature is determined (almost always, except for super specialty bulbs) not by the type of phosphors used. But by the amount of phosphors used. Typical home lighting LED bulbs use 4 or 5 phosphors. Each phosphor emits a different wavelength such that the sum of light appears white to humans. The wavelengths are around 510, 530, 575, 610, and 660 nm. These cover the range from green, yellow, into deep red. The amount of these phosphors combined with some of the LEDs true blue light mixes and produces white. The "Soft White" bulbs typically have more of these phosphors and emit very little blue light, emitting mostly orange and red, with some blue, and a tiny amount of green. The "Cool White" bulbs emit mostly blue with a bit of orange and red, and almost no green. The specific wavelength of the phosphors used is identical in all LED bulbs due to chemical and physical limitations, manufacturing technology momentum, and market forces. It's simply easier to standardize. These phosphors/wavelengths are also based on what our current technology allows. While other phosphors do exist, they are not used outside of research applications due to cost, chemical safety, etc. Arbitrary wavelength phosphors are not possible since it's based on the chemical nature of the phosphor itself. Similarly to how LEDs only come in specific wavelengths.
So what is different about "Grow Lights" The short answer is basically nothing. I do want to point out that there are the purple style grow lights that are comprised mostly of blue and red LEDs. These contain very little or no green and yellow wavelengths, as generally these are seen as less useful to plants. This type of grow light uses plain blue and red LEDs without phosphors.The type of grow light this video discusses is "full spectrum" white grow lights. It's generally accepted that full spectrum is better for plants. But there are some caveats I'll discuss below.
The "Full Spectrum" grow lights typically only change one thing: the amount of red phosphor relative to the others. That is, they use the same phosphors as above, but they contain a higher proportion of red. They also typically contain fewer phosphors overall, and emit more of the LED's blue light. This offsets some of the red light, so the light doesn't look red to humans. So more blue, more red, and less yellow and green. The electrical efficiency of grow lights is no better or worse than regular LED bulbs. The amount of light output per watt of electricity is generally 140 lumens per watt.
Now a note about plants. It's generally accepted that different wavelengths perform different actions in the plant. Long wavelength UV (350-400 nm) can help promote fungus and pest resistance. Blue light helps prevent activating the plants' shade response which makes long and leggy. This makes it more bushy, and reduces inter-nodal length. Generally 5-15% of UV and blue is sufficient, and more has little effect, except to generate heat and use energy (These frequencies are photosynthetically active, but are very chemically inefficient). Green, yellow and orange are photosynthetically active in the same way as red. However, they are generally less important as they are chemically less efficient than red. The one caveat to this is that some people claim green and yellow help produce better tasting and more nutritious plants. I have not done any research on this. Red is where the plant gets most of its energy. Except too much red, or infrared (>700 nm) can stimulate the plant's shade response, making it leggy, and floppy.
So now the million dollar question. As an engineer I want to clarify the goal of the grow lights. And I want to be specific. For some people, it might be that they want to grow the most plants in the smallest area. For others, it might be that they want to grow the most plants with the least energy cost. For others, it might be that they want to produce the healthiest, best looking plants regardless of energy or space consumption.
-- For me, I have little room. I want to grow plants in a small space with as little electricity as possible. But I don't like the purple color of red/blue lights. For me, a mix of cool white, and warm white LED bulbs is just fine, and will perform just as well as "grow lights".
-- For someone who wants to grow plants commercially, healthy plants with as little energy consumption. Red/blue lights is probably the best bet.
-- Expensive "grow lights" are for people with lots of money, who just want healthy plants at any cost.
I personally believe, after years of empirical testing (both of spectral measurements, and growing plants), that "grow light" is just a keyword that they can put on the label so they can charge 5-10x as much. I have never seen substantial difference in plant quality between fancy and cheap LEDs as long as the plants get sufficient light to begin with.
In all cases, the most important factor is how MUCH light the plants get. The sun puts out insane amounts of light. (generally accepted to be 1000 watts/m^2 on a bright day)(this equals about 100000 lumens per m^2). A light bulb will put out *maybe* 1/200 of this if you have it really close to your plants. You'd need about 120 LED bulbs covering each m^2 to equal sunlight intensity. The more impactful change you can make to grow healthy plants indoors is simply add more light.
Can you tell me what bulbs you're using or going to use to grow your plants?
Great write up ! Thank you for sharing your knowledge
Great information, thanks! Would love a video or write up on what bulbs you're using. 😀 I have four clear 4' T8 LED tubes listed as 6500K, 24 watts, 3120 lumens per bulb over my shelf and my plants are doing great!
@@Ryan_H22What are you planting now?
Bro you are awesome. Useful information. I read your comment more than 5 times to understand well.
For people who want to grow with household bulbs a little hack is to cut off the plastic diffusers exposing the bare LEDs. This greatly improves light intensity and throws a more downward beam which eliminates the hassle and cost of using reflectors.
If anyone in interested in more information. I made a 2nd video going over tips and tricks to using household led bulbs including cutting off this diffuser. ruclips.net/video/gy69VpdOpJo/видео.html
doing that can expose electronics that are not meant to be exposed. ie can cause electrocution or fire if shorted, the diffuser is also how these bulbs are able to get the light as spread out and generally useful as they are, if you are gonna cut diffusers just use directional bulbs instead and leave them sealed so nothing bad can happen, cause if it can it just tends to happen, its the way shit is, maybe not to or for you but for sure someone you told to do it know this
@@twistedsocal All important points I should've mentioned. Yes, the bare boards on many household LEDs are going to have exposed points with 110 AC and they absolutely will shock you if you're grounded. No different than a live wire.
Still, it's a viable way to make something virtually useless actually work rather decently for growing. Perhaps it's not the best idea for anyone who isn't somewhat handy and doesn't understand or respect electricity.
A cheap 6 socket bathroom vanity light with ~15 watt LEDs with no diffusers can easily cover a 3.5 foot by 1.5 foot area. Without the diffusers removed you'd have essentially 0 foot by 0 foot coverage, just not enough intensity.
@@harrypeterson9287 my bad wasn't trying to state the obvious but now a day so many people seem to be runner up for the Darwin awards so i felt it prudent to point out that decapping lights will make them a hazard and also make them far less tolerant to high humidity and moisture. I'm sure just by saying that, we prevented at least one house fire and possibly a death by electrocution. or so is the goal,
@@twistedsocal😐 so this guy that sells grow lights via his company basically made this video as a way to show a "budget build" from home LEDs and he takes off the diffusers on his build.
ruclips.net/video/XnIzB_8knLU/видео.html
He seems to know what he's talking about and I've tried it multiple times over the last few years on different bulbs. Only trouble I ever had was one bulb that started flickering but there's nothing to indicate the flickering was related to the removed defuser. The defuser is just a plastic done, the actual LED is pretty robust, ie outdoor LED lights can get water in them and still work 🤷♂️ You wouldn't be using grow lights in an environment they'd be in much danger of damage if you're not reckless.
Do your own research obviously but quick tip is squeezing the diffuser in a vice makes it pop off fairly easy vs trying to cut or saw it off.
Been using daylight led lights to grow lettuce for 5 years and has given me more plant mass than of those grow light rip offs.
Glad you've seen success with your chosen method!
@@humblegrowth only the difference is the taste. Having this kind of setup makes it taste watery bland, less sweet compared to the grow lights.
I've been researching grow light strips for a project I'm working on.
The "grow light strips" I've found are 3 red 1 blue for lettuces, 4 red 1 blue for flowers 5 red 1 blue for fruiting crops such as tomatoes, strawberries.
Can i grow singonium plant in room using led light ??
Hold on you can get household led bulbs with the same Samsung or epistar led chips in those grow lights you mentioned and easily find them at 4k. Then regarding density why don't you talk about when ten 10w bulbs are use together with the domes removed vs a 100w led grow light ?
If you mix warm and cool light you will get a good spectrum ,use warmer lights for flower closer to sun set tone the better ❤
I grew cactus, snake plants, succulents, etc with a daylight led bulb I popped the cover off of for years. The LED bulbs are super directional without the cover on them!
I have used 6400k LED bulbs to start seedlings for the past 6 years. Before that I used Daylight 6400k CFL lamps, but the arrival of the cheap LED bulbs, together with a good drop in power used, pushed me to try them. My main crop is superhot chillies that require a long growing season, so I sow early in the New Year, so that the weather outside has stabilised to 10c at night, and the plants are ready to move into bigger pots in my little greenhouse. I see no deficiencies in the plants, and they thrive in our living room until it's time to go outside.
Okay where is everyone finding their 6500K LED bulbs from? The best I've found are 5000K

aww thank you so much! My wife will be happy to see this, she keeps telling me that my best videos start off with my "Dad humor" as she calls it.🤣
My main issue is the cost/benefit. Grow lights are massively over-priced, and I don't think most people, even those who use standard house lights, believe you can get as good of results with those as you can with grow lights; It's just that if you can get good enough results for your needs, the cost becomes a big factor. For example, aquariums can have fairly affordable lighting, at least until you get to basically ANY of the spot lights, which is the lighting I prefer. Those things are like a hundred dollars bare minimum just because they have the "aquarium light" label. Instead, I use cheap GE outdoor 90w flood leds with the caps popped off; These lights have a second lens touching the diodes such that with the diffuser removed, they become spot lights that grow well even at a 3 to 4 foot distance. Of course most of my plants are shade plants, and I get a bit of (very diffused) natural lighting, so that helps. Even if I needed two or three times the amount of cheap lights to equal the more expensive ones for par, it may well be worth it. The more expensive ones are mostly for all the bells and whistles, appearance of both the fixture and light temp, and yes, slightly better plant or coral growth (based on what I've heard at least; they're out of my price range). And don't even get me started on the rest of the aquarium industry...

I have grown tomatoes under LEDs for years in a spare room. I started these Campari plants from store bought tomatoes ten weeks ago. Currently I have 50 green tomatoes growing on 3 plants in 5 gallon (self watering, wicking) buckets filled with soil mix, all sitting on common chrome metal shelving with about 6 LED strip lights ($15 ea., 5,000 lumens, 6000K color). The 3 buckets are connected to a float valve which is fed by a 5 gallon nutrient bucket, filled weekly. I move the lights up as the plants grow and will begin trimming the lower part of the vine, coiling them before they reach the ceiling. By spring the vines will be about 20 feet long. I get enough side lighting to grow greens close by. TIP: Use inexpensive thin silver Mylar "survival blankets" wrapped around the shelves to reflect even more light.
You are a legend bro. I also grow tomatoes vertically. Are you having any problems I can help you with?
I have grown dense huge buds using 100 watt equivalent with mixed spectrums 3000 and 5000. I grew a plant that it's main cola was a half ounce so these lights work best in closets and best in grow cabinets and grow box's. They must be close for good results.
I've been doing it with normal light without even researching it, and it works fine if you're not professional and you are passing tight times
great work!
i can highly recommend the 23 watt 2700k micro spiral CFLs from Sylvania. I've never had too much luck with any household LED. You could try them out and give a review for the folks on a budget.
They're the model X28161LV.
Walmart and Amazon have 7 way splitter sockets for about 10 each. Just screw it in the socket like a normal bulb and then screw 7 bulbs into it. Takes up less than a square foot of space. I just bought 3 and I plan on using a mixture of LED's in each one. Also, Temu has good prices for LED lights. I ordered 6 of the supposed 2000 watt folding garage bulbs. They use about 30 watts in reality but are a good source of side lighting and they have 3000k and 6500k versions for about $10 each. I ended up with a $30 price adjustment refund on my order for 6 of them. Some of the larger foldable LED's for about $15 put out 25,000 lux. I'm getting 10k lux with these up close and the lights stay cool to the touch. Connecting 4 foot LED shop-lights are great for seedlings and clones. I also use them as side lighting for the lower branches and they really do a good job. My 12 cubic foot closet it at 40,000 lux and 3600-4000 foot candles from just Led's. None of them cost me over $60. All of my HID lights are sitting in boxes as relics but I may pull them out for the last few weeks of flowering for an extra kick. Apple Betty, Glookies, Wedding Cake, Runtz Muffin, DosiDo #33, Skittlez, Mimosa Evo, Fruity OG Kush and Fat Bastard are the flowers I'm growing and breeding with. Not to forget freakshow is what I've crossed all of the others with. F2 seeds from any of these will grow 75% normal looking weed and 25% will have the freakshow leaf mutation. If you take a mutant and breed it to another mutant with the recessive gene active, all of those seeds will make mutant plants. So F3 seeds will all look like the Freakshow strain. Cross one with a regular strain and you'll have to repeat the entire process to make that cross mutant. Reading the first half of Genetics for Dummies taught me what was going on with my webbed leaf strain. Later found out it's Frisian Ducksfoot strain and we couldn't figure out why only some of the plants had the webbed leaves. Then I read about Mendellan genetics and easy peezy! P.S. I have a Ducksfoot hybrid (with Flo, G-13, Blueberry, Cinderella 99 and Runtz Muffin stabilized) pollinated by Freakshow. I'm at F1 now and all of the seedlings look normal as expected, but f2 something special is on the way with 25% being a freakshow and 25% Ducksfoot and 1 in 16 seedlings having both recessive genes fully expressed. From there I take a Superfreak female and clone it. Sex reverse one for female pollen and all of those resulting seeds will have both mutations expressed and the seeds feminized! The police saw my grow room and the Freakshow male and loved it! They thought that fucked up looking thing was some funny shit. With what I have invested you better believe I don't screw around with lighting and I choose LED's.
Very good hard work. I need to know which prodict u chooses from temo like picture.😅
I enjoyed video. I use LED full spectrum 32w bulb for seeds & green by GE for my plants at vegetation stage & then they go into the window for flowering! Works great
Lol, I used 6 regular bulbs and the buds were airy and foxtails everywhere. And the potency was little to non existent. But it was fun.😊

Wow this is so cool that Chris Martin from Coldplay has some grow light tips. Awesome man!!!
I'll take that all day!! Thak you!
Hey man! This video has more information in it then most places I've been searching online. Thank you so much! Also, would you mind answering a question? I have 6 led lights, each is a ufo flat surface led light that produces 21,000 lumens at 5000 kelvins. If I have these hanging at 10 ft, evenly spaced in a building that is 1500 sf, could they grow lettuce in 5 ft grow towers? You've got a subscriber!
Hey, Thank you so much for the Sub! so, to answer your question. With the high power output (21000 lumens=150 watts = APX 60-100Umols) The lettuce should grow. I don't think your growth will be anything thing to write home about as far as speed goes. But maybe teamed with the tower garden, I could be wrong. The 10 feet away is what worries me more. At that distance you would be seeing a fraction of the photon density that you would at say 1 to 2 feet away. You will get that 60-100umols at 1-2 feet, but at 10 feet I'd guess you would receive more like 10umols. Which might not be enough for an entire tower. Unless I just misunderstood you and you were saying the lights will be 10 feet from each other, in which case, go for it Elijah! Your Kelvin being 5000k should be just right for leafy greens, so your in good shape there. 👍
@Humble Growth Hydroponics Thank you for taking the time to reply! The towers are 5 ft tall, and the lights are 5 ft from the ground, so the towers are separated from the lights by 5 ft. Would you suggest I bring the lights closer?
@@elijahbrown7038 Since you are lighting an area rather than a single plant, it might be better to keep the light a little further away so that it can distribute even light to all the plants. Still though, I would move it as close as you can while still lighting the entire area. hope that helps :)
Exactly what he said. Thank you!
@@elijahbrown7038 Man, you’ve got to start wording your phrases so they’re easier to understand. You can’t get a direct answer, which means we can’t either, because your questions are highly ambiguous. It sounds like a question I’d like to know the answer to, but still don’t. Now, I have to ask for myself.
Just finished a grow of Runtz Muffin with 9x e27 Philips Core Pro 13W 4000k even with diffusers on in a 2x2 and had no problems.
Nice work!
You most definitely can have a decent grow, using Screw-in LED.
Remove the plastic Dome! Run 3000k and some 5000 k.
Migro did a pretty good test.
Awesome input. 👌 thanks. I may have to re shoot this one, I'm afraid I wasn't blunt enough in just saying "yes, you can" just wanted to make people aware of the benefits of a full spectrum grow light and what you would be missing with standard leds. Anyway great idea with removing the cover!!! Thanks for the great comment Mike! 🤙
@@humblegrowthjust run a knife along the edge of the dome several times to loosen the cylicon glue and then use the knife as a lever. It's a bit hard, but doable.
Agreed!!! I have had success with both household LED bulbs that were decapped and regular/high output CFL's growing cannabis. You just have to make sure to run several different wavelengths.
That being said, nothing made my plants explode with denser buds like a strong 2000W King LED light. You will not be able to get heavy and dense buds with household LED's, but you can grow very decent buds!
can i use those that have a monti colors and how many should i use
My next grow involves the following- I plan on using a total of 8 lights. 8- 4 Footers. One set is adjustable between 3000- 4000- 5000k, also the wattage is adjustable between 55 and 75. The other set which is primarily for vegetative, runs 40 w 6500k. In the middle part of the growing both of the sets will be on. I have faith that this will work well I cannot type down the entirety of this plan here LOL
Hye... I'm just curious. Did you executed your plan? How is it working for? Just wanted to know
This works. I've had so many successful grows. Besides the led bulbs, the last grows i used a few huge CFL bulbs on the sides of the plants, both for vegging and for flowering.
I'm curious about the electric costs of grow lights.
@@lebowskiunderachiever3591 - That is good information to know, thank you.
@@grandmajane2593 Not 100% about everything to be honest. I have been researching more affordable short term options for growing aquarium plants and having a few fish tanks. The main tank will be perfect in the basement, occupying a nonfunctional gas fireplace. Planning on having the "lucky bamboo" rooted in the tank and having smaller G.E. par 38 fruit and veggie (clearance now for $4.88 ) provide the light when the bamboo grows above the tank and into the chimney
@@grandmajane2593 Btw, I have experience with oregano growing but the technology has changed a bit 😎
@@lebowskiunderachiever3591 - That sounds so very interesting. I hope it works out well for you. I've been wanting one of those bamboo plants ever since I saw one on the counter at my local Chinese restaurant.
It's never correctly advertised.
Help! Is 'full spectrum' the same as 5000k? Can a 'full spectrum' bulb actually have a lower Kelvin number? I believe that even a 5000k build can have a narrow spectrum of light - if it is measured with a spectrometer, which I don't have. I am trying to light my painting studio in the best way... not growing plants. The difficulty is that daylight and 5000k may look the same to our human eyes but they will render color very differently. Any suggestions? - confused in Washington.
It's not the size of the grow light, it's how well it penetrates the canopy that matters.
Well said... ;)
Hi, I grow mint in outdoor greenhouse. I get sunlight from 6am to 5pm then I run T5 Led 6500k from 5pm to 10pm. You think this setup works for my spearmint or I am just wasting $$ ? Best regards from Honduras
My gol is for mint to grow faster
Hey man, you know those Philips first gen CFL lights You mentioned? I just took one out of a lamp in my shop after 20-some years and replaced it with one of those filament LEDs that uses 1/4 the power but is 5x as bright, lol
I use the Philips Hue system. Could I use these if I have them set for red and blue?
I am supriced how much my plant likes just a Ikea ledare 8w 2700k cri 90 bulb.
I think its the only thing keeping it up during winters.
excellent, that is surprising, keep it up :)
Thank you for the information
we now have smart LEDs which spectrum can be adjusted. It's not too expensive and is a good investment.
Shouldn't basically any light without heavy cooling produce a good amount of infrared? I wonder how big the impact of an normal amount of IR diodes vs the IR of the lamp as a whole is in comparison. In my experience plants really love soft diffused light along witha bit IR as the heat gives them a bit of a boost when growing tropical plants in normal household conditions.
I have a birds if paradise in a a wide north facing window, do you have a recommendation which LED light bulb to buy?

Im currently using fecida 65w 600l and they cost 65€ and have full spectrum Red deepred and bleu so they are doing great! It's great it used a minimum of electric and have no heat on thé led and have iron casing and have vent build in!? Amazing i say that we used to use 2000w lights in thé past..
Why are smart guys so 🔥😊
I'll take it! ;)
I am just trying to put some new light bulbs into the already light fixture I have so my plants don't take over by my windows. My husband doesn't want the house to become a greenhouse, and I need to sneak more lights in to grow more plants. 😂 So, I was thinking of installing in my basement office.
amzn.to/3VStMcZ and amzn.to/4iQa6QM are really great grow light bulbs, he will suspect nothing! ;)
That color chart is wrong. Plants use green light and need it. The idea that they don't need green light came from a flawed study from the 1970s, which triggered the market to make grow lights with no green or yellow light, which had sub-par performance.
Thanks for the information. You're right. I appreciate the correction.
New sub. From the Philippines 🇵🇭 I like your topic keep posting about hydroponics men 🥰💪
Thank you! I definitely will 😊 appreciate you being here and watching!
hey kuya may mga kwenstyon din ako haha
Be careful growing those Hemp plants hydroponically ;0)
100-150w led bulb that uses 60w 6500k works well for vegging the plant and fits in regular socket.
Good for house plants anyways.
Great video
Thanks!
Caution on the 36 watt SANSI grow bulb! Not worth considering. Their own ppfd slide tells us that, despite having 60 degree lenses, you get less than 200 PPFD at 1ft distance. That's horrible even for the wattage, with 63 diodes at that wattage, they sure are overdriving the LED's. The reviews on it are clear too - it will break very quickly. The only thing qualifying it as a "grow light" is its PPFD slide and the following upcharge.
The other linked lamps are far better. Also look around for High bay LED, and floodlights. just avoid the bottom tier efficiency ones.
You can. I've grown big plants from them
Did they produce plenty of fruit? I've been a little discouraged with my veggies, and flowering but not fruiting with my diy light array. Guess I need more "warm"/red leds possibly.
Back to the Roots 2pk 10w LED Grow Light Bulb White
From target any good?
For sure, solid bulb for veg. You will want about 10 of them for flowering though.
Thank you
If I use a growth lightbulb to grow my plants do I need a special light fixture to attach to the lightbulb in order for the growth light to work or could I simply attach the growth light bulb to a regular light fixture that I already have at home?
Simply use what you already have. Any led light emits synthetic photons that stimulate photosynthesis. So, you can use any bulb and light outlet. The important thing to consider is the light frequency (color, or also called light temperature). I made a video all about light color that will hopefully help. :)

Can regular led bulbs be used for reptiles?
Great information!!
Thank you!!
Yo, what about mixing bulbs? i got one blurple 200 diodes and 9 phillips led bulbs (each 8.5-9w 806lm) from 2700k to 5000-6000k?
Sure why not. They work well too, just see check your PAR values
very informative
Like... this theory's got back 😂😂
Does it work to use spotlight lamps?
I have a light fixture in my kitchen that holds 5 spotlight lamp bulbs and they become pretty hot when they have been on for a while. They are warm white with kinda bare fronts so you can see the diods. Does this work or should I invest in a real growlight instead?
(I am really new to being a plant mom)
I've had success in the past with cfl's in both 2700k and 6500k, from start to finish, though I didn't grow a large crop. Just what would fit in a 40 gal garbage can. 😁 I am trying to piece together a "very budget minded" set up with led's in 6500k. I'm just looking to start a few plants for outdoors, but being in a northern climate I will need to start them indoors until mid/late May. I don't think I'll be doing any flowering indoors so I'm just focusing on vegging... We'll see what happens later on, but for now I'm not looking to invest much into elaborate systems.
Excellent! Your on the right track, using "Cooler" light during early growth then almost all "warm" light during flowering. Should do the trick if you can get the photon density high enough. It really all depends on what you are growing. Using a 6500k would be a good overall light temperature, 5000k or even 4500k would offer a little more red light. Growing with a 6500k would give you a healthy, leafy, slightly bushy plant. The buds/harvest will likely be less than what you would get with more red light because red wavelengths stimulate photosynthesis more than any other. I would recommend starting with your 6500k then adding, switching, or using color changing bulbs to achieve closer to 2000k-4000k during flowing.
@@humblegrowth ya. I don't plan to flower with 6500k. Idk if I'm going to try flowering any inside the house or not yet. We'll see what happens when we get there... I am looking at possibly getting a ts1000 or similar. I just have to be mindful of the power bill.
Where can I find tube grow lights that are plastic? i purchased a HydroDesign hydroponic system. It came with 4 Sunco light bulbs. Setup of the system, i broke a light bulb in my hand, so I would like to replace them with plastic bulbs. I have another system that came with plastic tube light bulbs.
My best guess would be amazon. 🤙
I have a quick question. I live in a house built in 1958 and there isn't very good natural light. The windows in my bedroom for, instance, are 18in x 30in and there are 3 of them. one on either side of my bed and one in a coved part of my bedroom (my house has an odd roofline). I want to install light panels or something similar to make it look like there are more windows than there are. Will regular LED light panels be ok, or do I need to create my own using specific LED lights? I am a plant lover and really want to have them in every room, but as it stands they are all in or close to the picture windows in my living & dining room. I know this video is over a year old but I am hoping you might still answer. Thank you!!
Skylights are nice, if there is a place on your roof suitable for them.
My plant is happy. I have a very odd mix of lights. 😂
ohhhh I hear ya lol
It still bothers me a bit that all people who want me to buy grow lights are people who sell grow lights. But your explanations about the light spectrum were really interesting.
Glad you found the light spectrum chat interesting. Just to be clear I’m not selling these lights, I linked the lights on Amazon for you to view them if you’re interested. If you buy I make a commission of like $2 - so the value is really for you not for me.
HI can we use smart bulb as a grow light?
Would grow lights encourage mildew growth?
Not mildew, but algae. Mildew thrives in dank, dark places. Algae loves dank light places. Lucky algae is not harmful to you (it's actually healthy if consumed properly) unlike mildew which can turn into mold and become harmful to humans and animals. The main difference being, mildew is a fungus, with spores (eventually grouping together to create mold) the spores are what are dangerous to breath. Algae is a organism, just like us, similar to the single cell organisms that all life originated from. Regardless, you don't want either in your garden, so avoid light on your wet places, and dank warm dark places.
I have a question if i may ask. I posted a video just a few minutes ago asking this question but i will ask here to see if you can shed some light : ) on my inquiry. I have a full spectrum led light. i have both the veg an bloom on 100%. I used an app called Photone and it shows my light temperature is 12,000k. I understand there is a difference between the color spectrum and the color temperature. For a seedling or a plant in Veg, is there any harm to come from running at 12,000k?
Blue is your friend with younger plants
i have a question, have those led light i mean a bulb and has all those colors needed to grow, you think i could use each color for each stage of growing my pants
Yes!!! I built my own full spectrum customizable led grow light with 12 color changing led bulbs...it's pretty sweet I must admit.
@@humblegrowth let me not get way, but i mean its grow some sticky yiky some mari and jane type cultivation at home is it do able or do i need to try
I personally hate the blue/red sheen of the full spectrum ones. I am not a light sensitive person, but these colors just piss me off. So what I've generally done for my houseplants (mostly tropical greens, non-flowering). Is that, I use Airam Superlux LED in combo with Airam Plant lights LED (full spectrum. LED PAR30 835 800lm E27). The Superlux cancels out much of the visible to the eye blue/red sheen from the grow light, as the Superlux has such a powerful lumen and light spread, vs the grow light.
Perhaps a bit inconvenient, needing 2 like that, but I rather make that investment and be creative with the decor aspect of how to set it up in a pleasing way. In order to have the plants grow beautifully through the winter months (north of Sweden), while also still being able to enjoy a welcoming and cozy looking indoor environment.
Love this!
Can I combine the winter sun in Finland with LED lamps for better effect?
Yes absolutely
Even better solution are LED reflektor lights like the ones that are used in construction to light up the rooms. They are low watt and extremely bright. Also extremely cheap compared to grow lights
What do you think about normal house light bulbs for growing mushrooms they only require light for directional growth they don't photosynthesize
They grow better under the blue light spectrum
Sounds like a great experiment... Here's what I've been thinking and workshopping; 10 gallon aquarium on the bottom with a log cut in half, doused with spores then filled with dense fog once an hour for 15 min. on the bottom of the lid I put led strip lights that I can adjust the color of. on the top of the lid, plants with their roots in the fog. Thank you so much for the comments!
@@humblegrowth it does work.. I grow mushrooms. Any light source will trigger mushroom pinning. I just haven't tried complete Cycles under regular LED house lights. I'm sure it'll work mushrooms require the blue spectrum of light
@@ORShenanigans6186-c1x Know anything about "truffle" light requirements?
@@andybilakshow260 I'm not thinking they require lights as they grow underground.
I have a pothos and a tradescantia if I leave it near a open window with no direct sunlight will they still do ok in the room. I have them and also have a lot LED bulbs. I just want big plants. Any tips.
Can i use RGB as a grow light?
MICRO GROWING WEED 2×2 CONFINED SPACE CUTTING OFF PLASTIC COVER LED HOUSE LIGHTS RIGGING TO A 2×2 FT PLYWOOD 8 LIGHT BULB AND THE PLANTS ARE ALSOM ABSOLUTELY LOVELY
Is there a difference between a regular household 60 watt light bulb vs the daylight 60 watt daylight light bulb which brightness is 760 lumens. These are fairly new on the market.
i want the answer of this question 😢
Ok i have to ask coz I can't see anseem else commenting on it.....
What is going on with your videos sound?
I can't sit with it.....😢
How about cutting the tops off and putting 3 100w equiv. Led bulbs at a ratio to 3-3000k 1- 2700- 2 6000k veg and 4 3000k 1- 6000k and 1-2700k bud cycle and with this ratio you would get a very realistic spectrum and as for photon density. Make it 50 w /ft2. Is that not the optimum amount that is required for a top notch lighting system. Do this and you will have a serious good system only lacking uv/low red spectrum. 75 bulbs in a 5x5 and that will set you up with all the light to have a terrific grow for $300 or less! Throw a 400w hps in the mix at week 4 of bud if ya really want excellent trichome production. You can manufacture a light with a consistent 1500mmols/ on a 5x5 and with Mylar walls you can go 6x6. $300 to light a 6x6 is cheap and you can make smaller but just follow the 50w/ft2. Rule. Hope this helps people see you can use regular led bulbs when mixed in the right proportions. Try it I promise you a successful grow.
Thanks for the input!
I have 4 6500 k led daylight bulbs is that be enough for 2 plants i have wrapped the setup with aluminum foil but seedlings looks to grow very slowly kindly some one will can give advice how much i have need more until flowering stage
It's hard to say, but it seems like there is a lack in photon density. The sun releases photons that have been making their way out of the core, through plasma then travel 8 light seconds to earth and hit plants in the trillions. Photons are the result of colliding atoms in the center of the sun and contain all the energy we get from the sun. The plants have evolved and adapted to need a particular wavelength of photons for photosynthesis. Household led bulbs create photons through electroluminescence which cannot fully replicate the sun's wavelength of light. Full spectrum grow lights use several different frequencies of light to replicate it the best. House hold leds just can't quite do it. Tbh I created this video to encourage people to use full spectrum grow light bulbs instead, but it totally backfired and now everyone wants to know why it isn't working well for them... short answer, photon density in the proper wavelength cannot be achieved with household leds. This is why your plants are growing slowly, they can't fully trigger photosynthesis. Hope that helps... or maybe confuses you more... sorry
Your plants won't flower without the proper wavelength and photon density. This means you will need a lot more bulbs (like 10) at a "warmer" frequency (red light) for flowering. You will likely need several more lights to even trigger photosynthesis to get to flowering. Or you can buy a couple full spectrum grow light bulbs from Amazon and get there for sure. Hope this helps
@@humblegrowth yes I understand I'm also providing them 5-6 hours of sunlight plants growth is slow but it's growing I'm seen every pair of leaves after 4-5 days. But I really can't afford grow lights so hoping it grows in these critical situation actually it is the bcn critical its tough strain
@@humblegrowth can I send u some pics of my plant if possible on any platform i am really concerned
@@chaudharyhamza4570 Of course, I'd love to help you. Send them to Humblegrowthcontact@gmail.com
Trust me, if you said it at all, you’re not to White to say it. I see you my brother from another mother😊. You definitely have your sisters subscription and support, with that one line. Well, you also know your stuff.
week1 to 9 $22.00 for 24 led Household LED Bulbs works great
All depends on what you grow, ??
Ive a buddy who gets 60g out of 1sq ft from 33w house 2700k led and 15w blurple.
Its a mini steath cupboard. So they do work better than most pro growers realise. But it just requires very driextes light inna tight space.
tbh I'm no professional, but managed to grow marijuana with a singular 150w white led light (more on the blue light spectrum instead of red) and some periodic sunlight in windowsill it works fine, I'm in the northern hemisphere with a west facing window so i get the afternoon sunlight. covered 3 square foot 70 cm away from canopy of plants
I have two plants under 5000K LED spots that are doing just dandy bringing them back from near death.
good for mother plants, but not for growing flowers.
Love this! Keep em' going!
I grow beautiful plants with regular led lights
I'm black and I approve of the saying "This theories got back" lmao 🤣
You're awesome!!!
Grow lights= huge ripoff . I get 30,000 lumens from 3 led shop lights. All bud.
How much wattts?
Can you share name of item?
I start mine indoors it's a bitch to grow outdoors in the Florida summers
What part of Florida? I feel you.
@@JamaicanSaga - I remember when I lived there it used to rain every single day in the summer.
Thats why you put the bulbs on a board and create a bigger foot print
Great idea!
If someone is just using lights to start seedlings a proper grow light setup is a massive waste of money. This year to start my vegetable garden seedlings early I bought a 100w LED 6500k 10,000 Lumen shop light for $35 as the tubes for my T5 aquarium grow lights blew up. Despite only the small wattage increase I've noticed this year stems are much thicker than last year on my tomato seedlings with the T5 grow lights.
OK so if anybody has any extra grow lights around, please let me know just for like 2 plants I’m trying with a regular 800 lm LED lightbulb I’ve been trying in my window seal I’m dedicated, but need some assistance. Let me know n thanks
I’m on the wrong side of RUclips, lol. I have a bamboo plant in a basement office. What kind of bulb can I use for that without over paying?
lol amzn.to/42pAs6j these lights are solid bulb replacers that put out a pleasant color and have a relatively high PPFD. Hope this helps :) Let me know if you ever want to start a channel, this is my 4th, and I help people setup youtube business's with passive income streams based around their passions, as my other business. :) cheers
Can you get rid of the ringing in your videos its pretty distracting, good info though
lol yes, it’s gone from the new videos
Could you do one as bright white and one redish light? Like just the two bulbs next to each other?
Absolutely, that is a great idea to create your own full spectrum lighting environment 😀 👌
Uhh, the dome can be cut off.
I do a followup video. I will say though, it's not super easy to remove without a vice, but yes, doable.
you need about 10 led bulbs without the plastic covers be careful it can shock you if you touch them
Always very cautious, thanks for looking out!
So basically I just watched a really long ad
... how so?
I grow tomatos with 30w 6000k floodlights with no problem. Absolutley no daylight what so ever and $10 a piece
House hold led bulbs are the way to go, there cheap effective and they last for years, if you say they don't work, you have not tried them, you need to take the plastic dome off and you need to keep them about 12" above the plants, so if you want to cover a 4ft x 1ft you need to use 6 x 13w bulbs
❤❤❤
I dont necessarily use it for growing, just tricking my plants into staying in veg outdoor 😅
Fair enough!
With basic led bulbs growth will seriously blow, period, not enough spectrum available also, you can grow to finish without dedicated red spectrum, I used to grow with just metal halide hid bulbs, very blue, and it just results in denser buds etc, red is optimal but not a must to flower
Do you think a plant would grow better with a 5000 Kelvin or a 2700 Kelvin bulb watt for watt
@@slicktmi you know, watt for watt still isn't gonna be a defining metric here. Watt per watt LED outputs more lumens per watt than any other light source but has some of the worst penetration ability of any lighting source. Also, sticking to a single kelvin color temp only works for LED nothing else is that specific. Sure light bulbs claim to be of a certain kelvin but they have spikes in many more than just the one they claim sooo growing with an hid vs a fluorescent vs a compact fluorescent vs a cheap led vs something grow specific such as a spider farmer or a gavita pro (I don't even know if gavita makes good LED grow lights but their de hid setups are next to none) sooo if your asking if a fluorescent bulb will grow as well as an hid the answer is hell no, same with most led setups, no but at least with the high end LED setups they cover the needed spectrums. Still in my experience, de hid metal halide bulbs mixed with de hps bulbs in a 40 mh 60 hps setup throughout the entire grow will net the most yield and potential sweetness (think potency here if cannabis is your crop) if you leave out the blue side or the mh you will still grow large buds but not as dense nor as potent and will stretch the plant more. I prefer the closer internodal spacing and thicker main stock of a plant so it can support more weight and in turn will fruit more
@@slicktmi also if you are talking kelvin then you are just sticking to perceived color spectrum and typically the more orange/yellow red side of things yields more but, the blue is far superior in early growth pre flower so flower 2700 5k for pre flower just how it works, still led with high enough lumen can cause light bleaching if too close and still fail to penetrate for crap unless you do some serious pruning. But I have seen some led setups yield more than any hid setup I'm sure strain makes a huge difference as does the ability to keep the grow area cooler but I have seen nearly 3lbs per light off of a spider farmer vs 2.5 average off of gavita de hps. Don't have large scale mixed hid knowledge just smaller boutique grows with mixed hid and or using cmh or plasma setups. Never seen plasma used large scale but I could imagine it could do some rad shit since it is the closest thing we have to sun light in doors but the heat is a killer
@Josh Hall so when you say leds have a hard time penetrating are you talking like deep into the canopy or talking about the leaf itself saying that its not penetrating the leaf enough to photosynthesize?
@@slicktmi oh hell no the LED setups available today have killer abilities as far as growing like I said I have seen larger yields from high end (think 1k a light) setups per light than out of literally any other light source to date, I am guessing a large portion of that is the frequency tuned aspect of LED in general, they are very specific and not what could be considered full spectrum but if you add other wavelength LEDs to the array then you can quite literally tune a fixture to a point that just is not even kinda possible with any other tech available today. The catch is, different plants need different spectrum availability and most grow lamps are most definitely designed for growing cannabis since it is the ultimate cash crop (if you can afford the licenses and permits etc or if you don't mind still working grey market lol but you do you) point is if you want the same results with food crops I doubt that you can find fixtures tuned for specific crops so general tuning or cannabis tuning is the option, great if your growing tomatoes. Not so great for many other crops at least not from where I stand. As far as the LED ability to penetrate I simply mean to undergrowth so anything below the top canopy. Secondary canopy or u der growth suffers, granted it always lacks adequate light but at least with other tech there is enough reflected light to allow under growth to be productive and not make it mandatory to lollipop your crops. The way people grow now, veg is such a short deal, think a week to maybe 3 and right on to flower if grown from clone (gotta keep the killer genetics going and why wait for new seedlings when you can have foot tall babies in 7 days with clonex gel and foliar super thrive feeding sooo simple. So fool proof and sooo much time saved. Anyhow scrog or sog are a thing that has far out paced full term veg and low height plants going into flower with single bud sites can majorly benefit from LED where under growth and secondary canopy are not a thing. Ok I have rambled long enough sorry hope I answered you somewhere in here l
Ty but your brown btw where all shades of brown tones of brown ...look up your brown tone and truly wake our minds up
To grow what? Cress, Lettuce? HPS is what all the commercial growers use in all countries.
Prove me wrong.
For sure, high pressure sodium lighting is great for large scale production. You are absolutely right. But this video is more for people who want to keep there herbs, greens and houseplants alive just using lights they already have. If you watch the video, you see my skepticism as I always recommend using full spectrum grow lights. But the question is can you use household leds and the answer is actually yes.
Only Real Sunlight & H.I.Ds are will produce worthwhile yields.
I take it you didn't watch the entire video?...
