A hole for the exhaust? Like a passive exhaust? If that is what you mean you should reverse it. Fan sucking out of the tent with holes cut for passive intake.

i figured it out. i cut a 6" area next to the centraI gas heater in the garage through the tent, i put a piece of ducting hose next to the heater, air sux in from there ,sqirreI fan exhaust it. best thing about this is burnt gas reIeases tons of needfuI co2 for budding , this wiII be great for this winter. thanx for aII who stop by.
