Wow, I'm most impressed with your structure and the wood stove is an excellent idea! I think of the heating expense of a greenhouse and shy away from the whole idea but wood stove sparked my interest. We heat a lot with wood in the house but my wife wants a fancy, trendy gas fireplace thing and do away with the old stove and that would be a great use for it. I've scouted firewood for years and haven't been without in 16+. I can still get my firewood fix.
Hang in there with the pups, I think they have a good chance.
Thanks for the photos and inspiration.
