Why A Year-Round Greenhouse is part of This Permaculture Design
It doesn’t take much for those of us in temperate climate zones to imagine the allure for year-round greenhouses. Fresh tomatoes in January are compelling! A more controlled and protected environment in spring, summer and fall has real advantages as well. And from a small business perspective, what if we could produce enough fresh produce for ourselves and a handful of our neighbors 52 weeks of the year?
In a good permaculture design for an urban residence, a homestead or a farm, the first thing we seek to accomplish is the efficient storage of summer crops through root cellaring, drying, fermentation and other forms of preserving. But once we accomplish this… few things beat fresh produce in the middle of winter.
To get this done we need to design for the two major demands of plants that are in short supply during the winter months: heat and light.
Could we not take this excess carbon source, turn it into wood chips and with the use of these small gasification units, provide the energy we need? In effect we would be harvesting current sunlight and eliminating our need for oil, coal or gas while simultaneously sequestering excess CO2 from our atmosphere. Hummmm….
