So I learned to farm in upstate New York (and my family dairy is in Penn) so I feel you on the limited seasons. If I may- the trick is getting two layers of greenhouse fabric and adding air between them- a small fan/ducting would be enough. That airgap will buy you a TON of leeway....MI.. I generally am done come the end of Sept. Hell lows in the upper 30's tonight. Put too much time and money into my new outdoor tent. Like to see what I can do with it. View attachment 4687093
Otherwise look into Elliot Coleman's cold box designs...little brick glass topped enclosures for winter greens. He farms year round in Maine.
