We recently completed a 2-year study on a composting system designed to collect and reuse the heat, moisture, carbon dioxide, and nutrients from a compost system to grow in the cold season.
This video describes the process, study, results, and ways forward for others who would like to try this out.
More information can be found at our website, lowtechinstitute.org
This study was funded by USDA's Sustainable Agriculture Research and Education program.

As someone who has never gardened in your climate, my ideas are not terribly useful, but if i was going to force air through the compost i would look into using a portable diesel heater to pre heat the air. While that may seem to defeat the purpose, taking a 5kw heater and picking up extra heat from the pile to keep a green house running seems cost effective.

Thanks for watching. The compost pile produces so much extra heat, running a pipe from one side of the bladder to the other, pulling cold air through the warm space and then into the blower would preheat the air, too. Or installing the intake at the top of the greenhouse to catch warm air there. The heat is there, I just didn't capture it. :-) Next build would integrate that, though. Thanks again!
