I recently built a pole barn (36x48). I have a medical marijuana grow in part of the barn (30x36) and I live in the remaining area (18x36).
Here is the layout.
The whole building was insulated with spray foam. A wood stove was installed in the living room and up until this morning everything was fine. I think I experienced backdraft a few times but nothing serious. This morning it’s different. It's like a hurricane coming down and I think I know the cause. I need a fix.
The problem I suspect is the following: last night I turned on the inline fans inside one of the grow rooms to combat the heat caused by the lights. I have an 8” inline fan bringing air in from the outside and a 10” fan removing air from the room.
When the fans are on I can feel the air from underneath the door in the grow room being sucked in to the grow room. As soon as I turned them off this stopped, and the backdraft also stopped. I tried putting a towel under the door with the fans turned on but backdraft was still there.
I need these fans otherwise I can’t grow medicine for my daughter. She has serious epilepsy attacks and this is the only thing helping. We’ve tried all sorts of things and moved to Oregon for this reason.
I guess worst-case scenario I don’t use the wood stove. The house has spray foam and keeps it pretty warm. But due to the severe backdraft this morning, the house was freezing (it was 15 F outside).
Thanks for your time gentlemen.
Very respectfully,
Richard
