Here is a quick video about Photosynthesis and how deferent light waves are received by the chlorophyll causing different affects to your growth. All plants follow the same principles from Weed to Basil the lighting principles are generally the same.
Here are some links to tools I use

Here are some lights that I love that will hopefully suit your needs.
They are all full spectrum.
Inexpensive versatile led strip (I use in my nursery)
amzn.to/3IySskU
My Favorite 1000 PPFD light (over my Fogponic herb garden)
amzn.to/3VNvzNq
A fantastic bargain 2x2 tent light (I use to use on my cloner now on my hydro wall)
amzn.to/3XblStl
Inexpensive strip lights that work great vertically. (both tower gardens)
amzn.to/3Gp83kj
A high performance light strip that I plan to use in my Cannabis closet

Thank you so much for sharing valuable knowledge 😊
Amazing video! Thank you so much. My son has to do a science fair project on how different colors effect seed growth. I’m educating myself so I can give the best help on the project
This may be the best comment I've received ever! so glad I could help, best of luck to your son! sounds like he's in good hands.
You mentioned Blue + Red light as primary yet Cool White + Warm White are both just as essential!! I'd say their need is more in between primary + secondary 👈
Warm white and cool white are just light spectrums with more blue or red light in them. There is no such thing scientifically as "white light". "white light" is simply a culmination of every other light color on the spectrum. A prism will show you what colors make up "white light. Therefore, cool white light is simply every light color with a lean towards more blue wavelengths. and warm light leans toward red. Blue and Red light, and more specifically just red light, are the ONLY NESSICARRY wavelengths that plants need for photosynthesis. If you want to optimize your growth however you can add higher wavelengths like UVA and Blue lights during early growth, then transition to a higher PPFD with much more red light during flowering to really get photosynthesis processes going. Other wavelengths like yellow, green, and orange are much less used by the plant. Nearly all green light is reflected by chlorophyll (that's why plants are green) and yellow and orange light is often absorbed verry minutely as red wavelengths.
If you look at my thumbnail image, in order to create what manufactures call white light on there bulbs, you would combine all of the colors and subsequently create "white light".

Hope this helps.
......I gotta do a video on this for sure.
Thank you.
Awesome information. Thank you! New subscriber!
Happy to have you here!
Awesome video ...thanks a lot
of course! Thank you for watching ~
Thanks
Love the science, more please ❤
oh you just stick around 😉 Understanding the science really helps demystify what is happening. Then, YOU have the control!
@@humblegrowth I'm not into Hydroponics. But very much into learning how to give my seedlings the best start.
What about white lights or does that count as blue?
This topic has been on my mind a LOT as of late, so thank you for posting! The thought that follows this is… mirrors. Has there been any experimentation with the use of mirrors to increase the amount of wavelengths that are coming in contact with the plants?
Ive been thinking the same thing! Like, aluminum foil on sodes and ack to reflect the light.
BOTH mirrors and aluminum foil are bad for reflected light...as the angle of reflection is poor.....because they mainly gather and throw the light at specific angles. Mylar and flat white paint are far superior because they gather and reflect the light more diffusely.
How close to the newly germinating plant should the blue light be to get short, stocky 🍃 to mature?
Hey! I have a new guide addressing this on my site humblegrowthhydroponics.com that covers this!

Im trying to get my hibiscus plant to bloom. Will shining "warm white" LED lights on it help?
Precisely!
@@humblegrowth how many hours should I shine on it and after how many days of light exposure can we reasonably expect it to bloom? Thanks!
There are a few variables that will contribute to the plant switching to bloom. Allowing it to bathe in photons (light) will tell the plant that it is n a stable and healthy environment and can safely switch to bloom. Light and light frequency (color) plays the largest roll in photosynthesis, however, if the sol (or nutrient water) doesn't contain enough nutrients needed for bloom. If you are in soil a NPK soil test could help figure out your nutrient density. NPK standing for Nitrogen, Phosphorous, and potassium the 3 big ones, the mirepoix if I may. So, to answer your question, If you are trying to get a tropical flower like a beautiful Hibiscus to grow (My wife and I lived in Maui for a few years and grew very very fond of Hibiscus flowers) you will need a heavy dose of light, I would get the light bulb as close as I can to the leaves, maybe like 12 inches, And leave that light on for 18 hours a day! You should begin to see flower buds appear within a week or 2 max. hope this helped.
@@humblegrowth thanks for your kind reply. There were already a few buds when I bought the plant one month ago. Hence, I believe the soil mix is good and not deficient in nutrients. As there is very little direct/strong sunlight coming into my apartment, I placed the plant at the staircase landing area where it received stronger sunlight, especially in the mornings. I water it about once, sometimes twice a week with a fertiliser solution (appropriately diluted). The buds got a bit bigger and it looks like (at least) one of them was about to bloom. However, after 1 month out there “in the sun”, there was still no bloom. Perhaps, it’s the year-end rainy season, with less intense (and less frequent) sunlight. So, I brought it indoors and placed it on top of an open shelf. As my living room have already been fitted with Led ceiling “track” lights, I pointed two existing “warm-white” bulbs towards the plant. The track lights are switched on only at night (from 7 to 11pm), main purpose is to light up the living room, and incidentally as a “side-benefit” for the plant. I wonder if this arrangement would (in any way) help the plant to bloom eventually.
What if the light says full spectrum but is white?
White light actually contains several different colors. Primarily Red, Blue, and Green light make up what we see as "white light". All white lights can deliver a full spectrum of light. When a grow light says "full spectrum", they (should be) referring to the PAR or Photosynthetically Active Radiation. This means only to the light waves that the plant uses for photosynthesis. Basically, full spectrum is simply an umbrella term for LED's that have been optimize to focus on the wavelengths that plants use to grow. Really though, it's a marketing term if I'm being completely honest. I use standard LED light bulbs to grow ALL THE TIME. Hope this helps. 🤙
Just wanted to add... Prisms are devices that separate white light into all of it's colors, but lucky for us, nature does it for us. Rainbows occur when "white light" travels through droplets of rain that separate the light into all of it's color in a beautiful way. When you look outside you are not seeing "white light" you are seeing EVERY COLOR of light bouncing off of everything and into your eye. Blue light bounces off of blue objects and appear blue to us, and so on. In fact plants appear green to us because chlorophyl cannot absorb green light so it reflects it back. ok, I'll stop nerding out about light. thanks for watching :)
