nice! i need to try this out ! please if possible can you give me a list of what i need for this project? i am subscribing right now !
Sure thing! What are you growing? the type of plant and size of your grow space are pretty big variables in picking out the wattage and color temperature for your light.
These LED modules are a big improvement over the old CREE lights, and they are quite a bit cheaper as well. You just need to select the color profile for your plant. A blend of higher CCT (5000K - 6500K) and lower CCT (2700K - 3500K) is usually a good idea, with more high CCT used for vegetative plants and more low CCT used for fruiting plants.

The power supply will constrain the number of LEDs you need. For this video, I used an IDLC-25-700, which only supplies about 22W of light to the LEDs. That's not enough for a big healthy plant usually, especially if it produces flowers or fruit. you'll likely need something like this:
Power Supply: www.digikey.ca/product-detail/en/mean-well-usa-inc/XLG-75-H-A/1866-5628-ND/10129176
Note that those Samsung LEDs have a MAX stable current tolerance of 1.4A, which is what this driver supplies, so it might be a good idea to buy twice as many lights and run them in parallel, which will maintain the same voltage over each line, but cut the current in half. When you string up LEDs in parallel, it's also important to make sure that you have the same number of EACH color in each parallel line. circuits wired in parallel always have the same overall voltage drop, but some different LED colors require different voltage drops for a specified current. All that means is that if you have different ratios of different colored lights wired in parallel, one or more of the lines might not turn on at all, while the ones that do will have more current than they should.
@@autumnmaticcreations62 Thank you for the reply man! Your a legend... I am not growing at the moment but im looking to maybe try out my hand in growing lol... for this set up what you have provided me... What strain is best adapted to the lighting spectrum?
@@alionofengland4059 For my PC grow I grew Dwarf Lowflyer from Crop King Seeds. I believe I used straight 3500K LEDs from Samsung for that one since it basically flowers immediately after the seedlings stage (about two weeks in)
@@autumnmaticcreations62 i have read alot about the dwarf auto strains and using alot of them for SOG set up... What are your suggestions on a 6ftx4ft space filled with dwarf autos?
@@alionofengland4059 oof that's a lot of space. As long as you can water them I don't see a problem. They need very little maintenance and virtually no pruning.
This is one of the better, if not the best, tutorial on RUclips. It is clear, it is concise, it is to the point. It does what it needs to do without useless hand waving, preening in front of the camera, hyped vocals or other silly crap. Great job. Thanks.
I totally agree. I especially appreciate the absence of distracting background music. Kudos to you!.
The man is intelligently minded & not only do I respect him for that he's gone into depth detail on building a larger grow light costing a small fraction for what they sell for.
Thank you. 🙏🏼👌🏼
I work in lighting and I make grow lights. I would recommend looking up Flood optics to get higher PAR reading from your LEDs, Those look like the common nichia diodes so you should be able to find some. WIthout using flood optics to direct the light down like a beam, a lot of light with be wasted going in other directions being inefficient, your plant won't like that and they won't get efficient lighting to survive to harvest. this is cool though. just add some flood optics to the thing and you got yourself a great grow light. i would look into adding 1 red LED and 1 UV LED
This answered 80% of my LED light making questions. Thank you for taking the time to do this.
Probably the best, most practical video on RUclips about making LED grow lights. Thank you for this!
Great vid and explanation. Love the solder paste. Never saw that done before. This got my gears turning and opened up a world of possibiliites. Thanks!!!!
Just saw some in Home Depot the other day, I'm like huh, what's that doing here? Well now I know!
Thank you. You’ve answered a lot of my questions.
Wow that’s reallly amazing, I’m sure this opens the door for custom shaped led boards for some crazy grows
i wish i have seen this video 2 years ago. Thanks man!
Man that was dope. Mad respect for the content man.
Freagen awesome man thanks for upgrading the archives! :)
I err learnt alot about soldering from this one vid .... ty
Damn, this was explained in such a simple way, even I understood it. Thanks.
Good approach. To save time, one can purchase led modules on metal strips. I used several such strips attached with automotive thermal sealant to an aluminum c-channels, then made then attached them to an aluminum frame. Using a c-channel doubles as a poor man's lens, reducing sideways light spill and redirecting it downwards. Same as here with the power supply, same with underpowering. When the time comes, I just get them out of storage and put them above the stuff that needs to grow, like cucumber plants.
These lights double as work lights when needed as well.
Nice job great video with clear concise narration.
Bro I always wanted to learn this and you made it that much more interesting and easier.
Amazing info and very well explained!
Great video buddy, thanks 🤘🏻
Good job man . One of the best videos I have seen about this
Great video!
Smart kid! Thanks for sharing 😁
Dude you are awesome! Thanks!
Paused the video...i need to say this. I like your idea of using an induction cooktop for soldering...a real take away for me!Thanks
Thrifty engineering = happy engineering
Just found your channel and im pretty amazed. It combines my 2 favorite things ,weed and electronics. Keep going im exitet for your next project🤘
On the way! 👌👌👌
Lol just thinking the same thing. I'm an electronic tech since '83 and a chronic since '74. ✌. Just put up a diy grow bar myself on my weed channel. Check it out.
Ummmm growmau5............visit his channel ....he was one of the founders of bringing DIY led and weed to the masses.
You will be "excited" when your house is in flames too! You can't even spell much less make a light
Thank you for this great and simple info 💕👍✌
This was a super helpful video.
Dude that’s great info 👍💯💯
Good Job, looks like a pretty good grow light.
This video is extremely well done. Thanks a lot man.
Gotchu fam
@@autumnmaticcreations62 it really is well done. You wouldn't be a poor student if you could build grow lights for dc off grid systems. The demand is huge and the supply is nil. Put together some plug and go systems for direct alligator clip to a 12v system and mark up parts and give yourself 30- 40 an hour and you wont be broke long.
Super excited
My first time bumping into your channel and got interested in what your doing, thank you for the knowledge. liked and subscribed b4 I start watching it. God bless.
dude amazing video! gj!
Yes buddy I didn't realise but a lot of information in the reviews links included spectrum and all I'm subbing thank you very much
Nice work!!
amezing bro you open up new good way for soldering thanks
Thank you for awesome info. 🌼🌺🌸
Nice Job, Great Video Brother! Keep up the good work.
Finally, someone who sounds like they waited until AFTER making the video, to smoke the end product!
😂
a true rarity
you do realize that led grows are not just for pot...lol
Hahaha
@@davidfailing6631 you dont say?
By the way, I own two of those Duxtop induction plates. I love them. Great products.
Couldn't find the perfect light for my microgreens shelves so was thinking of making some but it seemed too complicated. Thanks for demystifying this process for me.
You got 'er, my man
Thank you so much for having a brain in your head. Thumbs up.
Great video dude 🙏🙏🙏
Please please you deserve a Grammy and Oscar bro thanks
You are a Rockstar ! This combined with mr green's video might get very interesting !
Brilliant !
Good video bro!
Nicely done. Your right, too simple not to build my own. I love all different types of orchids and African violets. Having my purpose built LED strips will make my life in the greenhouse sooooo much easier.
For us newbies, you went a little fast, both in speech as well as actions. Maybe on the electrical testing and soldering you could go a little slower at the beginning of a soldering run, then speed up as you run along the board. Just a thought. Thanks.
Super smart bro
Awesome video those led lights where way brighter than I thought they would be,i just may try this project👍😀
They are very bright 🙃 I grew my first cannabis plant with fourteen I think.
@@autumnmaticcreations62 that's kool asf ,thanks for sharing your knowledge I'm definitely go to try to make my own lights for my next grow👍
thanks a ton... you are a genius
I did not even know you could use LED lights to grow plants so thanks for the time and info .
Knowledge is power, Thomas m'boy
look for cxa2530 on aliexpress, they are still on of the best and cost only 5 bucks per led, you can drive them 30-40 watts a piece.
i would definitely like a parts list too if possible. have you tested the par or ppfd on the 1 bar unit. excellent video you explain things much better than other vids. i would guess you're going to be a professor 1 day lol
id love to see par readings and more diy light designs. love the way you do your videos. keep up the good work
@Glory to God then test both
@Glory to God you seem knowledgeable. So let me ask you this, what kinda percentage impact does water have on a lights par and ppf? I'm asking as I want to calculate fall off at varying heights in my aquarium but obviously measuring these values under water is problematic. And par is good because it will give you a good indication of a lights overall potential when combined with the data on colour spectrum for the led
@Glory to God read this just now. www.ukaps.org/forum/threads/par-readings-through-air-and-water.33214/page-2
You the man bro
recent build.. $9.99 for 600mAh driver on ebay running 10-18 "3W" leds
10 "3W" leds run $5 to $9 depending on colour
i used 3 colours, 17 leds, total under $30.
selected 660nm deep red, "full spectrum" which has a bit of 465nm blue and covers red up to IR , and some 415nm (blue-violet) to hit chlorophyll a blue band (most people miss this).
3W leds are actually 2W, apparently the convention is to call them 3W. top tip when drilling aluminium: keep the drill bit wet. aluminium tends to shear and chunk, if wet it drills 3x faster and much tidier. press some kind of dimple into the spot where you intend to drill first, to center the bit.
i don't like to use lenses because of the light reduction. these cheap star mounted "bead" leds still have a wiide angle, so build reflectors also.
Hello there, do you have an video on how you did that? Sounds interesting... wouldt like to know more about it..
Well done..
By the math, your LED's are 2.17W each.
I made mine using 1W Grow LED's already on a star plate and series two circuits of 50 LED's each then parallel those two. The voltage rating was 3.2V-3.4V (350Ma) for each LED. This made the voltage of the series set 160V-170V rated. This way I can run them directly from the 120VAC house supply through a bridge rectifier and a capacitor (220VDC 1000MFD) for voltage stabilization and to capture the RMS peaks of the AC which makes me end up with 156VDC +/-. This is perfect allowing headroom for thermal variables and utility company line power fluctuations.
I attached them using thermal silicone to a 4'X4' aluminum sheet that is .063 inch (1/16") thick. This makes a 4 foot by 4 foot light panel at 100W, although I believe I need to add some 3000k white ones for spectrum balance.
Great video.
I don't have any of the tools lol but still, I will save it for later
thank you much
I think I might give this a crack. My Budz will appreciate it. Thanks bro.
And you will be really high when all your stash is burning with your house, just pay the extra $20 bucks and grow, wow!
Awesome video. As many have said extremely well presented. Do you have a "black" wire coming off the DC negative end of the light circuit and going back to the source inside the square tubing? Thanks again!!
Great video you've put together friend. MAKE MORE! Lol. You have a decently huge amount of subscribers that want more of your content. Cheers!
'Afternoon, friend! Things have been slowing down a bit and I'm thinking of getting back into this channel. So the question is, what would you like to see next? 😁
Could you make submersible led light setup for aquarium purpose? ....... you do a great job with the videos 😊
just subscribed cool video I need to try this what would you have to power it with if you wanted to make like that but do multiple bars ?
If you have a thermocouple and a multimeter with a thermocouple input, you can do the reflow really well in a countertop convection oven.
Crank the temperature all the way up, and control the temp by cycling the power on and off.
Most counter top convection ovens won't get above about 380-400F, even though they might say 500F on the dial. I'd be wary of using the 500F setting because that turns on the broil heater which might over heat the leds.
@@kristenhansen1843 That is why you turn the temp all the way up and just turn the power on and off using a thermocouple. I've done probably 50 pcbs using the $7 Oster convection oven I bought in a goodwill store. I've never had any problems. I downloaded the recommended temp vs time profile from Kester, the solder manufacturer and tried to match it. That particular convection oven had no trouble reaching the melting point of the solder (370F for 60/40 Sn-Pb).
Great presentation. Could you give out a list of which size starboards and which LEDs for grow lights, thanks
hey man, great video, I'm gonna have cpl questions or 6x6 how many o the luminus cxm 27 cob's would use also with what kind o a driver. Thanks in advance.
Man truly nice and complete video. I have a question, can i moun 3030 led like lm301h on these crees? You got a sub anyway.
yes hi ive watched your video and found it very good thumbs up ! i just wanted to ask you if i can get or where to get the samsung diodes in strip form already assembled, what is better single or double rows, im canadian also in montreal keep up good work. why i ask is because im alittle intimidated building the diode like you did also i was told that it is possible to add like a magnifing glass on top of the diode is this correct and if possible
For real bro that's an awesome breakdown and an amazing video. You definitely sound super smart and I believe you when you speak in a technical sense.. I was wondering roughly how much does the whole thing cost to do it this way? And could you substitute that hot plate thing for a pan on the stove?
I like how you said you find that if you place solder on the pad it sticks better, as if you independently discovered tinning, lol.
Yeah cool!!!
Question on spectrum range for optimal plant growth. How would you rank these LEDs? Are the better ones?? GREAT PROJECT! Ohyeah, RGB, and RGBW LEDs? what are your thoughts on them in general and for plant use?
those blue handled clippers look just like the ones I got with my anet.
If I were to make an LED array like the ones from spiderfarmer (a square array) what sort of Mean Well would be required. Thanks bud for any help. Also, is that a 3d printer beside you? If so, what would you use it for? I was thinking of creating a Rodin coil among other things. Again thanks for any help. Great video.
Hi
Thanks for this informative video. I'm wanting to develop my own setup instead of buying and existing product. It's for a 1m x 1m grow space. What LEDs would be effective for growing a plant? And how many LEDs would I need?
nice work. You should check out the flower carbo filter for your next project.
Very cool! I am actually designing something very similar for my next system. Thanks for the suggestion!
AutumnMatic Creations no problem man can’t wait to see what you come up with
Great video how much power would I need for 6x6 to achieve 2w gram with hydro
Or should I go for 301h quantum boards thanks
This kid a legend haha
Nice and simple way to understand tks.
I would like to know if u can help
I need to wire an 12v led strip which has resistor built in it as a brake light on my car battery voltage which when running gives 14v so to get constant 12v which will not damage my led strip what resistor i need to attach to the + wire of the brake wire so i get constant 12v .
Tks
So, what is the bottom line here on savings over, say, a retail light of that size? Also what is the wattage of the one unit you made? And will the power supply run more than one unit, or is it just about the right size for just one? Thanks, and great job there.
Super
I've been thinking of using corrugated fiberglass roofing panels to make an 8x2 foot light using light strips. The issue I have is finding super bright led strips that are 3100k with some red. I think these would be better, but I'm thinking I would need a lot more than 11. Can you help me design a circuit and find a driver? Or maybe a 2x4 would be more manageable...
I am your 999th Subscriber 😁
Good tutorial and flow on instructions, only thing that was missing is connecting the two wires from the DC p/s to the "light bar".
heh; your portable inductive cooktop is step up from my super-cringe reflow electric skillet, I might have to steal that idea and upgrade. The skillet has successfully killed a couple boards with hotspots. Also not burning arm on edge every-time would be a huge plus (skillet has a 2 inch lip).
Hello. Thank you for taking the time to share your knowledge. This is by far the most useful video i have found. Very well explained. I have the time to build it, but not much money. I currently have 3 rooms, growing medical cannabis as a necessity. I currently use metal halide for veg and high pressure sodium for budding (1000 watt). Power bill is killing me and also heat. I wish i could afford the spydrx lights, but way out of my price range. My math is not good, so i am wondering if you could give me a list of what would be necessary to build lights to replace my current 1000 watt ( for both spectrums halide and sodium) If it is possible to link multiple sections of light, example 8 feet x 4 feet or 12 feet x 4 feet saving on drivers. As i said, i dont understand the math. I would like to build similar to a 4 x 4 foot light, or 8 foot x 4 foot or 12 feet x 4 foot. I dont feel comfortable designing my own, as safety is important to me. Any help would be much appreciated.
fcn hero! Imagine you want to build your own grow lights, google it, nothing, youtue, this guy.
Thank you m8
Thank you man, excellent work!
How can find out the best spectrum/LED arrangement (by type, not position) for a wide variaty of cannabis strains?
Would you reccomend building two seperate setups for vegetation and bloom or one setup with an on/off switch for red-spectrum LEDs?
I've read lots of info on grow lights and have drawn the conclusion that all these magenta "grow lights" are pointless, so just good white leds are fine. I go with high-CRI LEDs as my grow lights are used only in spring and in the remaining time double as work lights. Don't know if you find this useful but in any case, wish you luck.
Very Nice. Do you sale custom builds?
Hi, very informative thank you 👍👍🤓🤓👍👍. Do you have a cost breakdown, time taken to produce and comparison against a comparable purchased light strip? Also is the light emitted always suitable for seedlings / plants or did you purchase specific LED for plant lighting?
Is there a way to connect the big board (cluster of 25 starboards) as it was with the power supply as a single unit?
Hello, I would like to know how to connect multiple types of leds to the same driver. For making a full spectrum light the leds run at different current and voltage. Good inspiration.Thanks
Hi AutumnMatic Creations. Big shout out from Austin, Texas!
During these times I am looking to make some UV-C lighting with LED for my vehicle. I am a ride share driver, U/L and local Ride Austin, and I want to save on drips, sprays, and wipes. I would just need to turn on the UVC lighting in-between rides, and for about 30 minutes after ending the work day. I have a Dodge Grand Caravan, so I will be wanting to custom build the lighting to go in the back.
Can you advise me on using the accessory power from my vehicle. When car is off.. you get the 12.6 to 12.8 VDC, and when on it ranges from 13.5 to 18 VDC. I will need something that can take the voltage from the vehicle and give a constant current, as well as constant voltage of what ever is called for.
Any recommendations?
Looks like the ground wire is not connected. Are you planning on connecting it to something? Would the heatsink tube be a good place so that the metal components are grounded?
Thanks for video!
Did you measure radiator temperature?
Is 1inch aluminum profile enough to cool the system?
Hey Andrii, I didn't measure the temperature. It did get pretty hot at equilibrium (probably between 60 - 70 degrees Celsius), which reduces the efficiency of the lights a bit. Cree's and Samsung's 3535 LEDs are tough though, they should still last a long time even when they're running hot.
Thanks for the video! I'm going to give this a try instead of buying my next set of grow lights. Do you have any methods for water-proofing?
Thanks! Unless your lights are going to be in the splash zone, I would not worry about water too much. If you want to err on the side of caution, you could look into silicone sealing spray - just make sure it can handle high temperatures. Anything rated for outdoor use should be fine.
1. How do I know how big of a power supply to get? 2. Do you like getting everything from led express? 3. What ratio of different led lites would you get to create a full spectrum lites?
( The different colors)
Thanks for all you do?
Much appreciated, Michael
I'm currently building a similar set up using the same LEDs and star boards. Bought them on eBay already built. For 15 bucks a piece. There Abouts. I am curious if I have to run each color diode to its own power supply or can I use a constant current,/cv driver.
How do I match lights to heat sinks and what is all this I keep seeing about drivers? I didn't see you mention anything in the video, or did I just miss it? How do I know the lights I want for a grow light are appropriate for the rest of the equipment?
