That's pretty damn bright, man! About your wilting: your humidity might be a little high, too. Make sure to get mylar or that orca stuff around your box. Theres so much light being scattered and lost; try to gather it and bounce it to your girls.

I know your plants are pretty big, but in those three gallon pots they just look absolutely puny. I definitely might give this CFL beast you have a try..... use it to supplement what I've got. How's it working out for you so far? What's the heat like?
