While we don't get snow, or at least seldom, we do get cold here in NE Mississippi. I haven't researched it, but my guess was that we got below freezing 30 days (probably more), in the 20's 15 or more days, and in the teens 6-8 days. The solar blanket cut my heating costs by almost 50% last year. Since I don't really grow anything in my greenhouses from April till November, other than starting seeds and using one for the first week or so when rooting plumeria, I can just leave the solar blanket on year 'round. The greenhouses get awful hot regardless, and I just leaves the doors/vents open during the spring and summer months and run fans when there are seedlings/plumeria inside. I do use shade cloths during those months.
