my grow cabinet / opinions ?

Nice work man. I love stealth cabinets. I like your light fixture but you might want to put a reflector on top. With cfls, you're going to lose light from the top. Yea it'll reflect of the ceiling but you lose a lot of intensity by the time it gets back to the plants. I've got a similar fixture but scaled down. Check my sig for a link to my cab. My cab is very similar to yours, a bit smaller though. I've still got a few improvements to do.

Nice lookin cab there dude!
Check out my first grow in my sig.
There is a good DIY carbon filter in there.

I'll be watchin this grow!
