Greenhouse Heating Options

Cole_Robbie · April 7, 2018

I started with an external wood furnace, which I still have, but I gave up that idea. Even with a huge fire, I could only get 7 degrees above the outside temperature with a single layer of poly and 15 with a double. It took up a lot of wood, and messed with my sleep enough to cut into the next day's productivity.

Old-timers here use a small wood stove inside the structure, but one needs s dedicated space for the stove and plenty of room around it so that the closest plants don't get too hot.
