tomatoman Reviewed by tomatoman on . Exhaust??? I am about to purchase a 224 cubic feet tent. I am going to be cooltubing a 1000w hps light so heat is not a big issue. I am, however, curious about keeping the air inside the tent from getting stale. I will using an inline exhaust fan that has a rating of 424cfm. My tent is in a 22x22 room and I was wondering should I bring in air from the outside my house via ducting or will the air from inside my house be ok? Also, should I leave the exhaust fan on continously or should it go on and off in Rating: 5
