The boards and such as proper measurements. So you can go in and estimate how much the system would be to build if you took the time.
Most climates would never even require heat to grow all winter with something like this. The thermal battery/mass within the greenhouse combined with a though out design/orientation would enable this.

Katy Rose wrote:Thanks again for the additional info, Marty! The porch is indeed wood right now. However, our (tentative) plan would be to actually remove the wood, hopefully carefully enough that we could re-use it for a porch in a different location. Then we'd put down some kind of combination of rock and gravel to increase the thermal mass and build the floor level back up close to where the door into the house is. We could certainly consider pouring a small slab of concrete where the tanks would be located, which I think would be on the north side (against the house) to absorb heat from the house. We'd love to use the system to continue producing food through the winter... a tricky proposition here in Michigan! But such fun to think about.
