Good day all,
I've got a small Palram Canopia greenhouse here in NC (think we're 8a now). I put it together back in the spring, and perhaps naively thought it would hold heat (at all) at night. So far, the best I can manage is about 5°F above external overnight, with obvious gaps filled with silicon and extra greenhouse plastic on the roof.
The base platform is mostly full of dirt/sand.
It's not critical that it stays warm over winter, as there's nothing that won't come back or be regrown. But I'm curious if there's any good ideas besides adding a heater. The tumbler has active compost and there's a black 5 gallon bucket of water.
If needed, I can add heat in the spring when we do seed starters.
