Passive hybrid heated greenhouse temperatures so far at night 14 outside 54 inside by attaching it to the side of the house that has access to the basement's steady year round temperature of about 50 degrees. Insulation at the base of the GH all around and 2 feet down UNDERground is a big part here too to combat the frostline. If you walk away with one thing new its this, Do not underestimate the power of the frostline my friends. put in Insulation in the ground at least as deep as your frost line.

still a work in progress, though making promising progress...
