Hey there fellow winter grower. Im building a 20 x 40 atrium on the side of the house now. I plan on running a Wiseway stove. 16mm triple wall poly carbonate 6 x 24 ft panels for the roof. Bails of straw line the floor with an r value of 25 with process on top to store thermal heat. Im in Maine so we have about the same weather. Plexiglass may be better for a roof and allow more light in. I would double it up with an air gap though it may be much more expensive. Thermal glass is heavy. My side walls are some what glass. The 4 x 7 ft panels or a bit smaller are 160 pounds. The key is you need strains that do well in low light. I have a thread in the outdoor labelled 4 season green house with a list of strains. Master Kush and Kaya Gold are two popular low light strains as is Bangi Haze. NL is supposed to do well and is a great flavor and popular. Best of luck
