Hello Everyone, I'm a new subscriber so the first place I went was the Greenhouse forum. I searched for Pit Greenhouse but I didn’t find anything so I thought I'd share some pictures of my pit greenhouse. I built it about three years ago and have been growing happily ever since. It is a design of my own imagination; the foundation is poured concrete five foot deep with a gravel floor. It measures 12’x24’ and costs me about $20.00 a month to heat (55 degrees) under normal weather conditions in MO. It’s insulated with R-19 with foil overlay that give it another R-2.
