Overpressure Venting

OK, here is what I have..

I have an indoor swimming pool, with and sub room for my filter and heater for the pool. This sub room already has a 1'x1' box vent to the outside.

I am considering using the vent setup I already have for my grow room that is currently in my garage, basically put an opening from the pool room into the filter room and attaching my blower to draw in moist warm air from the pool room. I think this should cause an overpressure situation in the filter room and I can put activated charcoal into the vent box to the outside to filter the smell. If I have the room sealed, does everyone think this would eliminate smell from venting out? The room is 5' x 15' floor and about 10' high

I dont see why it wouldn't work. Just keep an eye on temps and your RH during flowering, botrytis is all bad.

Yeah, I live in a serious desert area, so actually the humidity from the pool room will make things easier, since there was no easy way to increase humidity in my original room
