Like a combination air-cooled hood and microgrow in one.
Could be worth a try anyway; heat in small grows is a real killer.
If I can get my phone cam working or some other cam I can get pics of exactly what your talking about.

This one is two different rubber maid containers. Plants in bottom container and lights in the top. In the top there is a piece of 1/8 inch lexan and a 4 inch duct fan for exhaust with passive intake. With 8 CFL's in the top, the bottom stays at room temp with only 1 PC fan for exhaust.
