Nice, that garlic is looking great!
Those miners should help keep things warm for sure while they are running, but that heat pump is a must have. The last thing you need are frozen pipes and a flood the next day. Been there once, done that, and never again! lol
I hope you won't need more panels and batteries as they aren't cheap, but it is less expensive that fixing a plumbing nightmare. That's for sure!
Yeah they are coming up nicely. Hah yeah frozen pipes are no fun, and indeed we shall see how it all plays out over the next year.
