looking like you're getting things going. always improve what you can. are those fans all exhausting out, or do you have some doing intake? if one is blowing out and one blowing in, switch the intake to exhaust. just make sure all your fans for air EXCHANGE are exhausting. pick up a small (4-6") fan for RECIRCULATING the air. you want negative pressure in there.

as a side note, check this pic for an idea of what my CFL fixtures look like. Total cost for EVERYTHING was about $40.00
