Ah, ok... well most of the cannabis grow guides out there are written with sorta out-dated info with no mention of how phytochrome works... that's some interesting stuff, now that I know a bit about it, I can look up more info.

Seems to come into better use when using LED's since they can put out certain wavelengths for the red (660 nm) and far red (730 nm). So then I guess proper manipulation of that stuff could yeild better results... all stuff way too technical for me to ever mess with.

anyways, thanks for letting me know about phytochrome!
