Basic physics. It is not invisible, it is reflected by them. This is no myth, it is science. Green is NOT USED BY PLANTS! They have no way to absorb green light as this is the wave they reflect and the color our eyes see. You could not be more wrong.
Only thing I know are there like a red white blue spectrum that has loads of trichs formations..

Here the first google result on the subject. There are many more.

I know several physics professors that would strongly disagree with that entire study. They would argue because of how our eyes work and how we see color. Since our eyes only see what is reflected, it is physically impossible for a plant to absorb green light. The same things applies for all colors. If you see something that is red, that is the color that is reflected. Post any google search you want. Ask a physics professor about physics, not a botany professor. ;)

"I know several physics professors" is not an intelligent argument. Light is transmitted by waves AND particles (photons). Try again.

They are my colleagues and probably have a good idea as to what they are talking about as they have been doing their jobs for well over a decade. We are not discussing transmission of light. We are discussing how color is generated and the spectrum that object absorbs and reflects (the physics of colors). Go back to the kiddie table. Nice job trying to make a point that has nothing to do with what we were talking about. Try again.

Leave a green light on during the dark period on your next grow and report back.

I already did a few years ago. I used an Illuminati Led that was hanging from a single outlet in just a 3x3 mom chamber with three short plants (these are the same bulbs that I use in the ceiling fixtures where the flower chambers are). Alas, they didn't know it was there. It was no surprise to me at all, but I wanted to make sure they worked and didn't hurt my plants BEFORE I used them. Do you think I just derive ideas out of thin air? I have tried more things with these plants than you could possibly imagine. People that know me, pay me for my time and value every word. You should too.

Sorry, but I'll trust peer reviewed studies performed by botany professors before I trust a home pot farmer's word.

Pay attention here:


The early perception of neighbor proximity is based on the detection of changes in the spectral composition of solar radiation that are produced by interaction of sunlight with green leaves. Leaves effectively absorb photons in the blue (B, 400–500 nm) and red wavebands (R, 500–600 nm) of the solar spectrum. Absorption in the green (400–500 nm), and particularly in the far-red region (FR, 700-800 nm) is weaker and many photons of these wavelengths are back scattered in the form of diffuse radiation. We are sensitive to the green photons that bounce off the leaves (that is why we see leaves as green), but we cannot see FR radiation because our photoreceptors are blind to wavelengths longer than 700 nm. The plant photoreceptors phytochromes, in contrast, are maximally sensitive in the R and FR regions of the spectrum.


Read that a couple times so it can set in.

Some photons are absorbed from 500-600nm .


Some means some. Not none. So plants do absorb green spectrum.

I brought the article to your attention, rest assured that I read and understand it.

Thank you.

Plants use all light colors -because sunlight has all colors in it.

Also, plants have a layer of anthocyanin underneath the chlorophyl. It is the reddish pigment that makes "purple" strains purple. If we see a purple plant, it is because the plant is reflecting the purple light to our eyes, yes…but it doesn't mean that the plant isn't absorbing red light at the same time. The "problem" isn't that the plants don't use these spectrums. they obviously do. It's the problem of human eyesight. if you looked at these same plants with a bug's eyes, then you'd see a much different pallet of colors.
