And for red and blue light versus growth or spiking...... Everything the plant is absorbing is going through the photosystem I and II. The NADPH and ATP produced has NO memory of what wavelenght hit the plant. The plant uses NADHP and ATP to "fuel" the growth and spiking not the light!
That was the scientist in me! The orchidgrower is more confused.......
I get the feeling that the suns UV light do something to for example rupicolous Laelia´s and Sophronitis to trigger bud formation. The protection mechanism in the plant for UV-radiation may produce something initiating bud formation but this is not investigated on basic level. And this should then contradict Ross statement that red light is needed for bud formation? ????
So Ross, do you have the references for the study of red and blue light or is it just hobbygrowers trials you refere to or. Would be very interesting to read as I have a professional interest as an assistant professor in molecular biomimetics.

I was under the impression that photosystem I and II require a certain wavelength of light in order to be excited, per se, and release electrons which are then used for photorespiration? Obviously they won't have a "recollection" of what light had hit it, but I believe that it has to be of a certain wavelength. For some reason, something around 700nm seems to be popping into my head. Yep, I was close, apparently photosystem I requires 700nm and II requires 680nm (I'd like to thank wikipedia...).
Anyways, I'm no botanist, or expert on the Calvin Cycle, but I do like me some molecular genetics! hahaha
Thanks for taking the time to post!
