The green color for the plant is the balance point between growth and flowering. Phytochromes, cryptochromes and chlorophyll (etc.) are receptors for green light, and they are capable of detecting and using this radiation BUT with very little efficiency (it is reflected in a large percentage). So... green light (~500-580nm) can then be a growth inhibitor if it shares a large percentage of the spectrum with blue and red. Since this will also be used, but as I said before with little efficiency. If we used a diode led with a high amount of blue vs red and very little or non GREEN (should have a percentage of green as it would continue to reach the lower leaves), it would be more efficient to achieve plant mass than using a white light led where green would occupy space at the expense of red-blue (Frits Went, 1957). In theory, if you have a white led and place a green filter, the plant mass of the plant will increase. sry my english.

The hypotheses at the beginning of the video about why plants developed to not absorb green light is interesting, but why would they have absorbed blue light? Doesn't the ocean reflect most blue and violet light? Which would leave mostly just red and yellow for plants to utilize

Can't we assume that millions of years of adaptation to the stable spectrum of sunlight (through evolution) make the plants grow the best when light approximates the sunlight spectrum ? I would bet on that: The lamp which replicates the exact sunlight spectrum between 200 nm and 800 nm makes the best plants. Of course it would depent on the genetics of the plant too: High trees (canopy trees) which are exposed to direct sunlight are differently adapted to sunlight than plants who live in the shadow of trees and woods (like ferns etc.).

Just as is in the animal kingdom, light can be beneficial & detrimental at the same time. The sun provides us with vitamin D as well as the nutrients for development. It is also the source of harmful radiation linked to cancer, & how many can say they never had to deal with a nasty Sun Burn. We protect our eyes from UVA & UVB, so not everything natural is good. Cuttings and seedlings do well & under glass benefiting from filtering of light and will have to be hardened off to tolerate full spectrum sun. I believe visible spectrum lighting is healthy for plants.

@@johnmoss8015 exactly, this is why I said "between 200 and 800 nm" since infrared light is of too low energy to displace electrons in the Photosystem 1 and 2 (in the thylacloid membrane). And UV light is of too high energy, it breaks weak bonds in molecules instead of just displacing electrons (oxidizing/reducing molecules). Infrared in the other hand accelerates the evaporation of water what may help to transport nutrients (transpiration inplants). And we recently found out that plants need UV light as a form of orientation ("where is up"?). But these two effects are in my opinion too much cost inefficient. And yes we are actually well adapted to the sun: africans or other people living near the equator have a dark skin because melanine is a good UV-blocker. Europeans/caucasians who live in the north had to decrease the melanine to produce enough Vitamin D because the radiation intensity immensly decreases the further away you go from the equator. So if an african suddenly starts to live in iceland he may start to suffer from Hypovitaminosis and an iceland-guy starting to live in Congo / making holidays often in the caribbean may develop skin cancer with a high probability. Because both have left the environment in which their ancestors adapted throughout the last 10'000 - 50'000 years

@@luca920 Interesting post & information that i am in agreement with. I would like to add that your comments support my perspective of duality (good/evil) of the Sun. The delicate balance of UV protection & vitamin D regulation where melanin is controller. Melanin levels also determine hair & eye colour as i am sure must be aware of. I have blue eyes & light hair so that means that i have a different setup for the controlling Melanin. So that means I don't belong in the Congo. I'm tall & slim so that means I didn't evolve in the high north. My skin is not overly fair & of all colours is hair (even a little grey lately}. I live where I was born approx halfway between the N pole & the Equator. Isn't evolution & genetics mind blowing. I certain the reason my skin is not pastry white is living next to the ocean, I have enjoyed a diet rich in seafood which provides another source of Vitamin D.

A wonderful experiment would be to grow plants using only green spectrum light and to use more than one wavelength to measure which spectrum of green is most beneficial in photosynthesis. As most grow lights specialize in either red/blue and warm/cold white LEDs. With experimentation and trail and error we may see a better efficiency with red/green/blue than with a sunlight spectrum. Thanks for all you do and all the inspiration.

The question I have is ; why do grow lights have some kind of dip in the yellow/ green spectrum? A lot of lights have a huge one. Most 4000k lights have the same orange/ red spectrum as 3500k, but better green/ yellow and blue performance. If additional blue (400 -500nm) and far red (660 -700) is added the green/yellow dips hard. Weird man, weird.

Yes the HPS spectrum has 45% green and was proven. Than the red and blue argument was constructed to sell early LEDs and green light was said to be useless. Now we are back full circle. However the low level of blue light in HPS means plant stretching occurs. CMH is a better HID solution

Green light is not as efficient like you said however it seems to be that what matters about the green light is the amount of green light. Small amounts of Greenlight tend to act more like Bluelight in reference to how the plant responds. Large amounts of Greenlight however actually tend to make the plant respond more in a fashion like it does to red light. I would definitely be curious to know why that would be.

Hi new to the channel. I've been growing for a long to outdoors wild. The ideal was about green light vs sunlight. But grown outdoor in the woods under nature condition. So, I took two 2-liter soda plastic bottles, cut the tops off. One soda plastic bottles was clear The other was green soda plastic bottle. I flipped the bottle upside-down and dug two holes the depth of the bottles. I pulled the bottle out to firm the holes soil . I put seeds in bottles then filled up with soil. I slip bottle back in the dug holes. When the seed start growing in the clear bottle, the plant grow fast and falls over, the plant also is white on the stalk with light green leaf. The bottle that is green. The seeds grow a little slower. The leaf is darker. The stalk is full of color's. Short thick growth. So growing seedlings under green is better? ? To veg is to grow under sky blue??

Few problems there. You were growing them in a space with no airflow so they will have been desperate for co2. When you grow in a green bottle, the reason it appears green is that it is REFLECTING green so primarily red and blue would be passing through to the plants. The sky is blue but sunlight isn't. The sun is A broad range of light with all spectrums visible and invisible to our eyes.
@high2towerlandrace39

I like your opinion, but your wrong. There is air flow ,forgot to say poke holes to get air flow. If no air flow the plant leaf touches the bottle and the condensation gets leaf wet . Then the seedlings die from rot. In the early stages of a seedlings out in the wild, no help at all, the seed always pop's and shoots upwards then falls over, under only sunlight. But, using the green dome out in the wild, instead of direct sunlight, makes the plant stronger more colors and thick. Without the green dome or light you can't achieve this result with direct sunlight or indoor light that bright. Outdoors in the wild there is no green here in February and early march. It's all black and brown and other light tan colors ,the ground still has permafrost. Black absorbs sunlight and the ground starts to thaw. This is when seedlings start growing under ground. As the soil thaws out the seeds tail starts drilling deep in the earth. Some will be a foot long and have three leaf on them and are solid white. When the time is rite, the plant will pop out the ground green leaf real thick stalk and the colors of black blue purple pink on the stalk. The same happen in the green dome. Also, under the dome,during the winter,the temperature was 19°f degrees and windchill factor -11°f degrees outside, still growing like a hot summer day. Green dome or green light does make a difference in growing.

Hi guys so i was just thinking about green light and why the sun even makes it. Do you guys think that the sun makes green light for the purpose of purple plants as anthocyanin absorbs green light better then red and blue. I hear you on the extra lower leave penetration and im sure there is more to green light than just those two things but i wonder if purple plants play a huge part in why the sun even makes green. i would like to see this test done on a purple plant like a Perilla frutescens
