Didn't he say an 8x4 space? 2200 watts in a 4x4 space would probably be a different story (and overkill/inefficient).

a window AC unit and a DH framed in so that the exhaust goes outside of the gro-box does wonders. Don't knock it till u tried it. I bought an AC and a sophisticated exhaust setup, installed the AC, then realized air-cooling the hoods was frivilous... I returned 'em the next day... I run exactly 70-75 degrees, but it might be different in your climate/conditions.
