Hey,
My first time writing in, I do enjoy looking over all the posts and replies.
I live in the Black Hills of SD and last fall the garden club went into Alliance Nebraska and visited a "greenhouse in the snow" where the man had dug underground about 4 ft and then piped about 70 ft of black 4" tubing into his underground greenhouse. He used polycarbonate above and the right angle to our latitude and he has been growing lemons, figs and other citrus for years. I'm not remembering his name off hand, but he now builds these kind of greenhouses for schools and residential use too. It was a great field trip to go on.
I am planning a greenhouse in my lower level, with a rocket stove to keep the chill off and more skylight windows to bring in the light.
I would love your books to give me some more ideas before jumping in with both feet. Thanks for sharing your wisdom, with fun!
