Well I'm looking forward to seeing this progress. I'm probably not a lot of help at this point, I've only researched and toyed with LEDs. I've found the way that makes the most sense is to use 3 and 5 watters. 10 and 15 watters make the project much more expensive for the same amounts of light. I'm sure this will change in the near future. I don't think proper LED grow lights exist, though a few come close (SnS). I'd build my own for sure.

Are you familiar with rockwool? If not, I suggest not using it. It's hard to work with and in general it sucks, though many people seem to like it. Clay pellets are much easier, cheaper, and safer.

Bob is worried that LED might not work for a mature plant, but I disagree. Depends on wattage, viewing angles, and spectrum. We have just begun to scratch the surface of what is capable with LED grows. What I've seen is just not quite there yet, but it's very promising and getting closer all the time. Maybe you can be the first to really make something big happen. I think it's real simple. Use a lot of 465 in veg, and a lot of 660 in bud. Maybe a little 300 at certain times, and maybe some 735 so you can have an extra 2 hours of light in budding, or maybe not. Just blue and red will do just fine if set up properly.

I'll be watching. BlueBear is probably in the ball park about people not responding because this is relatively new technology. We'll show em.
