and for the can fan and carbon filter- you would need to hook it up so the air travel out of the grow room into another room? correct! Or can you get away with just hookin up the the can fan and carbon filter and not have it running into a different room-just running in the same room.will that still clear up the air if i did it that way. I know sounds stupid but not my spot. dont wanna be cutting and renivating the place if just keepin it in the glowroom will work?
