This is as good as a vacation in Florida! And a whole lot less expensive. When the weather is really cold outside like single digits, inside air temperatures here can be in the lower teens. However at the soil level the temperatures seldom go below freezing. This allows a variety of cold tolerant salad greens like lettuces, spinach, cress, kale, chard, etc. to thrive in the coldest months. I've walked in here on a cold morning and found everything frozen stiff. Several hours later with the sun shining and everything thawed out and growing, I could work in short shirtsleeves. We can eat this kind of thing for most of the winter. Last year in one six week period we sold about $750 worth of fresh salad greens off of an area no bigger than an average parking lot space, approximately 150 square feet. That is about 1/2 of the space you can see here. The greenhouse dimensions are 14 x 24 feet.
