I've got a 6" blower going through a 1000w light venting to the outside through the wall via basically a dryer vent. I'm growing in a 4' x 8' closet. Works well for my setup. Keeps it nice and cool even in the summer. I'm sure others here will have some more in-depth info for ya...
johnsonr81 Reviewed by johnsonr81 on . best way to ventilate??? I am running 2-600watt SunPulse 3k in 2-8" air-cooled hoods. I have a 8" 720 cfm fan that I will be cooling the lights with. The room size is 10'x13'x7.5' and there are no windows, just a door. The air in the next room is a consistant 62 degrees. My question is this: What is the most affective way to keep this room COOL with ventilation??? Smell is not an issue. Rating: 5
