winter ventalation

[rbregn]

The room I am building is in an out building. The building doesn't have heat on all the time, although the room will. How can I control the odor without sucking all the heat out of the room. It gets damn cold here in the winter.

I would use a carbon filter and maybe an ozone generator. I have kind of the same setup. My room is isolated from everything, no incoming or outgoing ducts, windows, anything. In the winter i use the heat from the lights to warm the room, and space heater at night to keep the temp steady. I use a combo carbon/ozone filter and just filter the air right back into the room for recirculation. If it gets to hot in the summer, i have a small standalone air conditioner, which is also a dehumidifier. I found everything i needed at home depot.

The air conditioner was kinda pricey. That DID have to have an exit vent because of the hot air created to make cold. Not much I could do about that.

Do you have to have CO2 if you are cycling the air in the room? I have a cold grow area that I don't use in the winter as it is too cold here.
