You could always go get a door and replace it with the one there now. You can cut holes in that door for ventillation because its yours. Then when you move throw the old door back up....:wtf:

Just remeber to use enough ducting to connect when the door is opened all the way. Also place the exhaust at the top of door. Simple solution..Invest in the exhaust this can make or break your grow..right now its breaking it.
