I certainly understand that premise, Dave. Several of the posts were from women who were going to do the (bulk of the) GH building, and a 12' long, 4x6" piece of treated lumber is awfully heavy. All my greenhouses have a 4x4" foundation, anchored by 3' long, 1/2" rebar, placed approximately every 3' and driven at angles. The rebar is attached to the 4x4's with metal straps, the kind used in building rafters. The greenhouses may blow away but those foundations won't move. It is really important to have the foundation level and square. I spent far more time on the foundations than on building the GH's themselves.
So far the Solar Blanket covering is doing what I hoped it would. We have already had 9 nights of 20's (all in November!) and the prediction is for 4 more nights in the 20's next week. This kind of cold for NE Mississippi is unheard of so early in the season. The bubble wrap appears to be holding the heat in and keeping the cold out.
