Greenhouse “heater”.

Don’t know how well this would work up north, but looks like it could work in southern Ontario. I could also see it being modified to work with bird coops.

Nice idea!

Interesting

I'd be concerned about spontaneous combustion? I've seen straw go up and it's not pretty.

Yes, it is interesting. I would also wonder if it would attract rodents.

I had the same thought....my composter (which is barely thawed in mid-winter usually) is full of mice and voles.....and my greenhouse is constantly being invaded in winter by mice and voles trying to stay warmer.....to combine the 2 and then try to have anything green in there would definitely be a recipe for disaster for me!

and i can't see a pile of leaves spontaneously combusting in the middle of winter here, but i could in a thaw-which we have quite often. i've caught our manure pile steaming and getting close on a couple of times that we had a mid winter thaw with some sun. it heated up crazy fast.....
