When we had temps in the upper teens/lower twenties with wind chills in the lower single digit range it only dropped to about 40-42 degrees in there so I can live with that. I have the thermostat on the radiator heater set to kick on when it drops below 55 degrees. It's been averaging in the 60's and 70's in there during the day, but we've had a very mild winter so far. The greenhouse is about 11 X 8.5. Wish I'd thought to insulate under the floor when building it, that would have made a huge difference I think. One of the issues when living on ground that is not flat!! I still wouldn't give it up though. I love my hillside garden.
