I'm trying to absorb all this as fast as I can, and.. my brain hurts. Mother, Salmayo, DogsNova, Has there been a formula established as to how long it takes for red(and how much red) to convert phytochrome to only absorb far red, and then how much far red it takes to convert back and how much time that process takes?

Do I have the whole concept wrong? It seems this whole thing is taking advantage of being able to control light frequencies indoors and using red and far red to bounce the phytochrome back and forth unnaturally to feed constantly and speed up growth, while keeping blue seperately controlled.

I do not, at all,understand how introducing yellow, orange or green would make sense. If the plants photosynthesis of light is much lower rates at those frequencies, why not just use that electricity to add more red or blue?

I do understand UV-b is debated to be usefull. If one were leaning twards wanting to try some uv's in that range, would they have to go in during the blues time slot?
