I wish I could make screenshots of my thermometers from various points in the last few days. I've been attending closely to the brutal cold, mostly because of how it might affect the greenhouse. Even when the low temp was down to 13 outside, and with no solar energy available to collect, just geothermal energy kept the greenhouse above freezing.

But last night, when it got down to -4, the greenhouse came down to 23 degrees. Oh noes, Cee, will it kill your plants? Maybe; but they're cold-hardy broccoli, leeks, carrots, Asian greens - it's not like I'm trying to grow tomatoes in there - so I'm not rushing in with a space heater, I'm just noting the data. And right now, the temp in there is back up into the 60s - while we're at the today's high of 16.

There's tinkering yet to do - I bet in years to come, I can do even better at trapping the heat - but I believe I have made my point.

Oh, and just because it amuses me: the broccoli was intended purely as an experiment, to teach me when I would need to plant it to get a yield. But now, in January, when it gets a mouthful of sunlight a day, it's producing heads. With salvaged glass and lots of insulation, I have turned the seasons on their ear.
