I plan on having a vent on the top of my coat closet to vent humidity . I'll probably use one of those dryer venting tubes to redirect the moisture towards an exit in the attic. But I'm sure some moisture will leak. Is it a big deal if moisture gets up in the attic? The heat up there should probably quickly evaporate the moisture right? I'm thinking about drilling a hole on the ground to vent cool air from the bottom of the house up too. (House on raised foundation)
