I have a dilemma .. I am using a 16x20 outbuilding to house a small grow, split into separate vegging and flowering rooms. I live in Michigan so the temps vary wildly between winter (sub zero) to summer (100+). I'd like to find a way to vent my cooltubes into my growing area during the cold winter months, but then redirect that hot air outside when it gets too hot in the room. I have a separate exhaust with a carbon filter constantly pumping flower room air outside and pulling fresh air in through a filtered passive intake.What is the cheapest way to do this? Any ideas at all would be greatly appreciated, thanks!!
