I’m about to say screw it and just insulate my attic. I spend a lot of time, energy, and money, just to keep my room a few degrees cooler than I want it and a little less humid than I want. Once summer hits it will be warmer and more humid than I want it, and I’ll still spend a boatload on energy costs
I can’t use a tent because I’m in a Detroit bungalow attic so the roof is sloped in multiple directions. Currently I use a hodgepodge of grow tent pieces for the walls, a ceiling piece is hung along the slopes above, with a second outer layer akin to a mini lung room, made of heavy and wool blankets. It keeps the extremes at bay but I’m at the mercy of the weather. Due to the passive nature of the setup I’m constantly refilling humidifiers and spend a lot of power on heating air that escapes anyway. Come summer, the attic is shaded most of the day but the grow room itself still gets quite hot without opening the tent up and I don’t want to do that mid flower.
This is a rental house. That is my major hesitation. It’s not the growing it’s the fact that I don’t want to spend my own money insulating the attic for his benefit. He won’t knock off rent for it since he doesn’t want or need it done. I think I’m gonna say screw it and do it anyway. Nothing fancy. I’m thinking about 100 sq feet of R14 should be enough. I’m not even gonna dry wall it, just install the insulation.
I’ve been talking about doing this since the first grow in this room. I’m gonna keep my eyes out for insulation deals now that I’m thinking about it not in the dead of winter
