Comfy at -28 F
Wow, it got really cold last night. My thermometer said -28 F at sunrise. Inside it was a comfy 68. In the greenhouse, low and outside was right at freezing and high and inside was 40. The 5 kW infloor heat has been running continuously and has also been circulating in the greenhouse floor. A nonfreezing greenhouse is a good thing.
