What is the best way to seal off a door to keep the smell of a grow room inside? I'm pretty sure weather stripping would do a pretty good job around the top and sides of the door, but what about the bottom?
Back when I was growing in my parents' house (bold and stupid both) I had a locking closet with a hinged door. I hung a blanket on the inside of the door frame, this was large enough to cover the sides and bottom of the door. Ventilation became a problem tho.
