I have learned a lot here, but this is one thing I still don’t quite grasp. I always thought the more air exchange in a grow area, the better. But some people do intentionally recirculate the grow area’s exhaust back into the grow area. This surprised me when I first seen about it. Then I got to thinking that may be a good way to help heat the 4x4 tent I’m going to get when it needs some heat this winter. Or at least reduce the amount of heat needed from the ceramic heater I’m going to use. I was thinking about tarping off a small area in my basement for the tent. Maybe figure out a way to insulate it better without actually going through the trouble and expense of building an actual room. Then I could heat that small area with the ceramic heater and exhaust the tent directly into the small area I make. I could control the air exchange between the small room and rest of the basement.
I’m White Widow rambling now. Sorry.
So I’m interested in hearing about anyone’s recirculation methods. If you wanna talk about it.
