I sense I may not be around much longer to say this, so I might as well get it over with:

Why not try to find a volume discount on one type of white LED and see if you can build a stronger white light for the same price as all the fiddly 10-different-wavelength plans? So what if it's a few watts hungrier than the others for the same effect?

I wouldn't mind experimenting with all white LEDs in the future.. (like perhaps one all-white grow vs. a multi-color fixture of the same cost to build) I just won't be posting about it on this forum, most likely. Too much bitch-fighting around here. (not specifically in this thread) If you have any other good places to discuss new LED options, hopefully I'll see you there when the time comes.

Used to be on a forum for some seed bank, that got rolled over into some other larger forum eventually. I don't remember it being quite so bitchy as it is around here.. but hey, it's been years. Anyway, good luck with the LEDs. Rated a bunch of these threads up for ya while I could.
