It’s happening! Work is underway again on our new heated nursery greenhouse.
It is that time of year, when we finally have time to work on projects that we can’t get to during the busy season of planting, harvesting and marketing. …(and then there’s Christmas and all its related activities…)
You might remember Phase 1 from this earlier post.
When this is all done, we will have a place to call our own that we can walk to, after several years of hauling soil and seeds and trays to an offsite greenhouse in the next town over.
This is even more exciting, as we are experimenting with sustainable methods to heat it. There will be a double, inflated plastic layer that fastens into this double channel…
And it is to be heated by a pile of working compost that’s soon to be built behind the cement block wall on the North side. Michael has welded up a steel tube manifold that they’ll bury in the compost. The two open ends will emerge through the concrete wall inside, at either end of the greenhouse. A fan will blow air into one end, and out of the other end will come air that has been heated by the compost. Since compost gets up to 165 degrees, we should see a significant warming effect inside the greenhouse on the coldest of winter nights. This blower will be set up on a thermostat, so it only kicks on when the air cools to a certain level. We will also use a woodstove for a backup.
By February or March, we plan to start growing trays of onions and leeks and celery. We will definitely be getting back into using soil blocks too!
