So I sold the little one and got the 12'X8'. Everything was wonderful. Built the new GH in October and it was ready to go for Mar 1st, the magical day that there is long enough days for a GH (11 Hours Daylight)
Well, I was not impressed when a week into March we got nailed with severe cold for a week. No exaggeration, -30ºC, which is -22ºF. There was a sheet ice on the inside of the plastic panels. My baby petunias were in trouble.
Googled insulating a GH and found the quick & easy was bubblewrap
