I agree with TLeom, I was about to say the same thing. It looks great, you're doing a fantastic job. The only one thing I'd recommend doing is moving it up so it's only a few inches below the lights. The CFL's won't get nearly hot enough to burn it or even really dry it out, so you can get it nice and close to give the plant optimal om nom. That encourages it to stay nice and compact and sturdy, and not get too tall, thin and reachy.
*Edit, you beat me to it clayma. Agreed.
