[I can't edit my first post?]

Instead of 5 plants, I've decided 3 plants for every group of 5 30 watt CFLs.

I also have another question, if I start flowering once it gets around 12" (assuming it looks healthy), will having lights just from above be enough? Or should I have from the sides too, or would that cause leaning? I would think the top leaves would take up most of that light, and a sufficient amount of light wouldn't get to the lower leaves.
