Greenhouse

[QUOTE=Pabstman;16798034]I was wondering, Up in the north (mi) if you were to dig a pit say 4.5 Ft deep, (below the frost line) dry stack a perimeter wall with CMU block. Install styrofoam sheeting against the outside of the block and put a greenhouse over it would the heat from the ground be enough to heat the greenhouse?[/QUOTE

Where in Michigan?

I doubt it would "heat" it, but if you insulated it well, insulated the ground around it(unpacked snow would work) and double glazed it the hole may get into the 60's in the day and the mid 40's at night. Southern MI may get warmer. I am basing this guess off of digging graves in the late fall when the frost is only about 3-4 inches deep.

You could warm it more by digging it a bit deeper and filling the bottom with a mix of straw and manure then soil on top of that. The manure decomposing will create heat. I think the idea is called a hot box or hot frame.
