In January it was getting harder to keep the porch warm, so we ran a lightweight rope shortways along the ceiling and hung a couple of pieces of row cover fabric from it - folded over the rope and secured with big safety pins, and used vintage glass and ceramic insulators to weigh down the bottom edges. This reduced the space we were heating by 8' x 10', which helped.
By late January we decided the glass jars just weren't able to retain enough heat (in a real greenhouse they might, but through two layers of translucent plastic? Not so much). So the Ashwaganda, Lemon Grass, Ginger, and Turmeric came in, as well as some of the more northerly plants that were looking a little peaked. All of the jars and bottles of water are under the plant tables in the dining room, with some in windows or around the radiator in that room for some extra heat.
The Lavenders, a mint and a savory are still out there. On warmer and/or clear and sunny days I'll uncover them, and at night and on colder days they're covered with a couple of lightweight curtains. I've got them all bundled together in front of the downstairs bathroom window, so any heat that might leak out from there goes to them.
Good enough for about a month...
This week it's gotten very windy, plus we finally have an actual polar vortex. I was working on something in the living room this morning and noticed motion through the porch sliding doors' curtains...oh look, the inner layer of plastic at the far end of the porch has blown down, and the outer layer is ripped to shreds! Happened sometime last night or this morning. The row cover curtains, such as they are, are still in place, and on the inner side of the enclosure the temperature is 20F -- considering it's 0F outside plus whatever the wind chill factor is, that's kind of amazing.
Can't do anything about it today, because it's too dangerous for human beings. Repairs will be.... interesting. The outer layer of plastic had been wrapped around the wood frames and then we installed each frame and secured them to each other. Tomorrow it's supposed to get up to 20F outside and also less windy, so I can lower the inner sheet more and try to tape the outer plastic sheeting together. Then the inner layer goes back up -- probably with some felt weatherstripping run along the top in a solid line, not just dots of it nailed in place (and more tape, of course).
Next month things will warm up some -- enough that we can look at using the porch again.
Been doing some research on glass greenhouses, heating, etc. We're considering splitting one of the greenhouses in half and using it on the south face of the porch. It'll be a big project, what with doing moisture control under the porch, leveling the ground around the porch, digging a cold sink, and more.
