That's pretty cool with the fan and the light. I was wondering exactly how it works. Is it filtered for odor, and the glass will be off the hood, and it sucks air past the bulb and out the fan. Or does it blow into the light?

Also if it were me, I would want some reflectors on those CFL. You are probably getting a lot of light wasted, going out the sides and even up. I'm guessing it would double the light reaching the plants, but who knows. I don't think anyone has found out yet what the shape of the light intensity is for CFL.
