So i have a great laundry room in my apartment to flower in...of course im using the dryer exhaust for the exit for the air, but my problem is the entry for the air...There's a drain for the washer that's 1 1/2" or 2"...i put my hand above it and i can feel fresh air leakin in...i thought about taking a wet/dry vac and stick the suction tube in it and take off the motor from the vacuum container so air will blow into the room, but i thought that might be overkill...does anybody have any suggestions?
