Do plants use more light colors than we realized? What does the latest horticulture research mean for grow lights? What’s the best color spectrum for growing plants? This video is all about Light Quality. What effect do different light wavelengths have on plants and their development? Do plants need UV light? How does Far Red light effect plant growth? Do plants use green light or is green light wasted energy? These questions are answered, along with scientific research that you can read more about, depending on your level of interest. 00:00 – Intro 00:32 – Kelvin Color Temperatures 01:28 – Visible Light Spectrum 01:39 – What is PAR Light? 02:38 – Do Plants Use Green Light? 04:30 – Benefits of Green Light For Plants 05:07 – Photomorphogenesis 05:25 – Do Plants Use UV Light? 05:51 – Do Plants Use Far-Red Light? 06:25 – How Plants Use Photoreceptors 07:11 – What is ePAR Light? 07:46 – What is the Emerson Enhancement Effect? 08:33 – How Plants Use Green & Far-Red Photons 09:07 – Is Full Spectrum Light Good For Plants? 09:36 – Custom Light Spectrum vs Plant Shape 10:57 – Is White Light Good For Home Gardeners? 11:59 – How Do LEDs Make White Light? 12:44 – What’s the Best Light Spectrum? We’ll take a look at the visible light spectrum (a portion of the electromagnetic spectrum). Why is it better to analyze grow light colors by their wavelengths rather than using generic Kelvin ratings? This video answers: What is PAR light (Photosynthetically Active Radiation)? It also looks at the McCree Curve & the Emerson Enhancement Effect. And we’ll see how to define ePAR (Extended Photosynthetically Active Radiation).

Using my old fish tank leds for my vegetable starts. Has an individual led color assortment. Shows the curve in the app based off what you kelvin you choose. Also intensity is adjustable. 4600k ideal for algae lol. I think I went for 6700k and the plant vegetable starts love it. As long as you buy a full spectrum for for when they flower
I call this my country learnin, but I already reckoned that plants would grow fine under regular light, seeing as that’s what we get outside, where nature is..
That was a great video with concise explanations. Really made it easy to understand. Thank you!
Your chanel is definintely the best thank you for such class!
Plants reflect the light that they dont need a little clue for you.
No, that “clue” is misguided. I suggest watching the video.
Y si la planta es daltónica?
i got fluffy buds with led
Then you used sub par led. Bc I grow rock hard nugs
Plants need UV for plants to be more healthy for our bodies.
Excelente vídeo, muito interessante e instrutivo, vou usar esse conhecimento para fazer uma lâmpada led para meu aquário.
It makes sense tho as white light has all different wavelengths and it reflects back the green.
Purple would mean all the light is absorbed.
When plants absorb 100% of white light, they appear black.
what about the purple led panel, enchanced with 4k led bulbs? it was pretty good for me, but i always worry to use that inside of a tent
Why dont you go wacky-wonzo science mode on this and measure the width of whatever microscopic thing on a plant absorbs the light? Matching that in one way or another would be a bad-arse way of giving each plant their optimal lamp
Very interesting video, thanks for sharing all the related papers too 🙂
I have a very rare type of migraine that resulted in a stroke. I saw that straight red and blue can cause my migraine symptoms to worsen. I am hoping the full spectrum I chose will work. ❤
First, get a good solid grow light with white, red, and maybe blue leds, then start adding separate Far-red, UV-A, and RGBA led strips. Much cheaper and easier than trying to find one fixture that has everything.
