Thanks Crawdaddy. I look at LED's now like big-screen TV's...there really isn't one too large. As long as you can control the heat, getting more direct vertical coverage can only be a good thing. My 700 has done an excellent job covering this 2.5'x3.5' area and I've no doubts with a little better lst I could improve on this grow so far. All the nugs are hard as rocks and so sticky it's almost dripping off lol. It's hard to see in the pics, but while little sis has gotten impressive lately, she has a few inches between bud sites and a good bit of exposed stem. Whereas big sis has slightly smaller main colas (she was topped, remember), her bud-spacing is so tight you can't see any stem on many of them.
Given the last 12 weeks, if I had a 4x4 square area I wanted to cover, I would look at the 900 as a minimum and the 1200 as optimum for my uses.
This grow is spectacular GOV. I agree with your statement can't go wrong with bigger. I read once that you still get quality bud from CFLs just less of it compared to HPS (something about light penetration) so I'm guessing it would be the same with the LEDs the more wattage the better and the more LEDs per unit the merrier for our little plants. This is the exact lighting method I need and I was going to go with the 700w but you got me thinking bigger is better might even go for the 1200w or 2 700w.
