The greenhouse in below-zero weather

8 Dec

It is a chilly one here in Northfield, MN. After a fairly warm November and December, we’re settling into the seasonal norm of well below 20 degrees F. We were incredibly interested to see how well the greenhouse did on a sunny morning with an outside air temperature of -2 F.

Guesses? Guesses?

The greenhouse is a whopping 28 degrees, which is 30 degrees warmer than the outside air temperature. We don’t know whether or not to attribute this fact to the amount of sun we’ve got or the insulative layer of snow on the sides. Either way, we’re incredibly pleased!
