The title says it all!

Porkbellies - you don't want to go less than 50 watts/ sq.ft. 4'x5' if you have a rectangular reflector; a little over 4'x4' if you have a square one. You don't necessarily have to completely enclose the grow area - a 4'x5' grow area in a 10'x10' room is fine - but the grow area/room does have to be completely light-proof.
