More lights = more buds, that was pretty much my thinking. Heck, I'd have put a 600 in there if I thought I could handle the heat, but I thought 400 was a good compromise. As it turns out, I think I probably could use a 600 in there, but that's okay, as I have the 400 HPS and some sidelighting CFLs too -- that's probably pretty close to what a 600 would give me, since I have better control over the light on the edges of the rectangular area with the CFLs.

And you can call me anything you want, as long as you don't call me collect!
