well is it intake or exhaust if its intake and you have no exaust that could be your problem heat rises and cold+co2 is heavier then air meaning will be low to ground which is where intakes should be....but 250 cfm should suck alot of air also...

its on exhaust..but i found out a earlier that it is a 80 cfm and the 6" one i was gunna get is 250 but the whole i have for intake is about 6" in diameter. Do u think if i got the 6" it would be to much wind force for the plants.

I use a 6" inline centrifugal fan (EcoPlus) rated at 440 cfm, but have its speed set lower than that with a little device called Dial-A-Temp, and have no probs. It's a bit noisy, but I can live with it. Just means I have to turn the TV volume up a bit higher.
