Welcome! Nice greenhouse. I would love something like that--I've always thought it would be awesome to have a greenhouse that was warm enough in winter that you could go sit in there, maybe take a book, and have your own little sunny oasis surrounded by snow. I'm guessing it would be too expensive to heat (I live in Minnesota), but makes for a nice wintertime daydream.
Anyway, enjoy Steemit.
Yeah, I don't heat it in the winter, too expensive. I live in the Upper Peninsula of Michigan, stuck between Wisconsin and Lake Superior. It's too cold at night here to start using the greenhouse until about the end of April. I have some passive heat storage in the greenhouse that helps keep the greenhouse a bit warmer at night, but if the outside temps go much below freezing, it loses heat pretty quickly.
I'd like to have a sunroom attached to the south side of the house, it would be easier to keep that usable in the winter.
