Im gonna grow weed in my attic. (its winter and cold outside. like 30s and 40s) But when i go up to my attic, it is as warm and any other part of the house. I know this is a good thing, but i am worried about the smell. In my attic i feel air circulating all around, as in cool air. My attic is closed tight but i was wondering, when the scent gets strong, will it seep through the vents into the house. like will people be able to tell that there is a weed scent?
