I exhaust from the tent into the room. No direct to outside vent. I may have to do this in the summer but not yet. The room is large enough that I’m not overly worried about this.
Humidity though…
I have a dehumidifier which I use sometimes to keep the humidity in check when it’s 90% humidity outside. I can usually get it down to…60ish but at night, when it’s cold, the humidity can drop to 35-40.
Given the circumstances this is the best I’m able to do.
