So i am using both of my bedrooms upstairs one for veg one for flower. Now my question is inbetween the two rooms there is a little open area at the top of the stairs with 2 little doors one on each wall. These doors are about 3 feet tall and i opened them and they are little crawl spaces. The house is an A frame house but from the roof to the wall is about 2 or 3 feet wide where these crawl spaces are. You can see insulation but it is covered by a thick black tarp. My question is can i run my exhaust for both rooms into these crawl spaces. ME and a friend were talking and we thought there were vents in there somewhere to let the heat out of the top of the house? I dunno. If i exhaust out there will i cause harm to the house or mold or anything like that?
