Plants don't see, period. They respond by phytochemical processes. Light is light is light is light, period. Photons are photons, there is nothing special as you are attempting to point out, it's just that plain and simple. Get to my level in optical physics and photobiology and I think you'll be racing to edit most of your posts.
Hubris does not suit you well.

I was at a hydroponics class last week. I proposed the led concept to our instructor. A man whom carries a PHD as a title. His exploits include 25 years in the agro-genetics division of a few different seed companies (corn,sow,cotten that kinda thing) as well as some time in academia. When I told him what I had read on the internet about 2 color grow lights....................................HE ROARED WITH LAUGHTER.

The simple fact that led take 2-3 week longer to finish should let us all know that something is missing. There is room for investigation, all the answers are not yet know. And most importantly there is no perfect.
