What's up guys? Quick question...please help. The grow room is about 700 cubic feet with a 440 cfm exhaust fan. The intake is passive. To cool the room, there is a portable air conditioning unit when on high setting blows 456 cfm. Medium blows 396cfm and low blows 336cfm.. Will the exhaust fan suck out all the air before the air conditioner cools the room? How should I set the two for them to work together properly?
