Yes indeed, I would like to see them. Plus, hubby is very interested in what we can do for our green house with respect to solar. We have one of those modular jobs that is against the house.
So we open the sliding door and step into the greenhouse. This is useful for extending the season or starting early, but we’d both like to be able grow some stuff in the winter there.
However, in Missouri, it’s too cold and the electric bill is already pretty high, so we’d like to figure out something. Not sure we get enough sun for solar though.
Back in my 'hippy-dippey/bell bottoms days', there was Scott and Helen Nearing who used a solar greenhouse to grow crops in Vermont for 10 1/2 months of the year.
They were both in their early 80's, but both very active, and taught sustainable glass berm greenhouse construction, and I thought they established an educational foundation.
The ideal setting for the greenhouse was partially subterranean(built into a hillside), facing south, south east (SSE)direction to catch the maximum amount of winter sunlight.
They used a stone & concrete floor, several 55 gallon plastic barrels (painted black), and natural stone wall behind the barrels as a heat sink, and heat storage.
If they could grow crops in winter in Vermont, I imagine that anyone could use the same techniques to grow crops in more hospitable conditions.
