Billy, there is absolutely no doubt that the solar blanket covering helped a great deal last year. We had the worse winter I can remember. This year has now started out to surpass last years horrible cold. I am considering covering my two greenhouses with another layer of solar blanket, at least on 75% or so of the total coverage. I don't know that it will help, but what the heck, I have extra solar blanket material and I might as well use it.
