You should have a good fan. I would suggest a Hydrofarm 265 active air fan. It should be hung inside the tent,blowing out with one of your flaps at the bottom open. That will be your passive intake for fresh air as the fan exhausts. You will need a thermostat with a piggyback plug to turn your fan on and off as the temps. rise and lower. Don't use a timer with your fan!
