That looks great. Do you have a way to vent it, for when it gets way too hot in there?

Not yet. There's a hardware store that sells these pistons that extend when they reach a certain temperature. They're meant for greenhouses. A friend says they work great, and require no electricity. I plan on cutting a window in the side and connecting it, or I could connect it to the roof, or one of the doors.

If it gets too hot in the greenhouse while I'm still heating the house, I could easily have the temperature controller blow the hot air into the house
