Running a 4x8 tent with 1 1000watt hps would like to switch it out 2 600s on a splitter. Have a 440cfm fan pulling through a carbon filter, a hood and then vented outside. I ghetto rigged my ac vent in the room to duct into the tent at the bottom for fresh air and a bit of ac. Anyway with all of this and just a general fan to move air in the tent im still reaching 85 at the canopy. Any ideas on how to get it down another 5 to 10 degrees?
