I live in zone 9a so my winters get to 20°F for a few days at a time, but it usually stays ~30°F for multiple days at a time. If I'm lucky it will warm up to 50°F. I'm thinking of buying a 6x8 greenhouse from harbor freight, because my highland Nepenthes collection is getting out of hand. I believe the greenhouse uses double wall polycarbonate panels. So what I want to do is winterize it so I don't have to spend a fortune in gas/electricity to heat it over the winter. If anything I want most if not all the heat to be provided by the sun.
So I had a few things I was wondering about. I heard some people use bubble wrap as insulation. Does multiple layers offer more insulation than a single layer? Could I also combine mylar emergency blankets with multiple layers of bubble wrap to provide even more insulation?
I plan to keep highland Nepenthes, Heliamphora, Brocchiana, and any other carnivorous plants that would survive highland conditions.
