So with out the carbon srubber on the temps are at 85.6. I moved the fan down to the botom pointing upward and the temps went up to 85.8 to 86.5. WTF am I doing wrong??? Where can I get a good (cheao) exhaust fan from (online)? My exhaust fan moves 240cfm and it's still not enough I thought it would be for the space in the box. Could it be there is not enought air coming in? I need all the help i can get.. Will the plants be ok in 85 to 87 temps?

I'm lost...Help...CFL Grow Ok hereā??s the thing I have a 2ft X 2ft X3ft box (1/4inch plywood with 1inch X 2inch framing) raised off the ground 2.5 inches. I have 8 cfls in it 4 are 5000k (hanging in the middle in an X pattern) and 4 are 6500(one hanging in each corner). I have an exhaust fan (6inch fan max cfm 240) it was sucking from the ground threw a 4inch dryer hose(kinda squashed to fit under the box) which I thought was decreasing the performance of the fan) so I moved it into the door of the box about 10 inches Rating: 5
