Hi! Tracey is right. I bring them in from Nov 1 to May 1. I have a propane heater that I run on either end for nights that get frosty. It is not at all air tight and with only 4mil plastic, it cools down to outside air temps very quickly. It is way too cold here. Even a well-insulated glass greenhouse would be very expensive to heat here.
