Durable
Our DIY Passive Solar Greenhouse kits are designed for year-round use in the Northern Rockies. They can hold up to 8′ of snow, and withstand winds above 100mph.
Items Not INcluded with kits
Each kit contains everything needed for the entire greenhouse except items listed below. The kits also include a list of materials, detailed instructions, a full set of architectural plans, and unlimited phone and email support. Lumber, corrugated metal, and door are not included and can be purchased locally.
The cedar 4x4s can be placed directly on the ground; no foundation necessary.
The interior of the North wall will be insulated by reflective foil and 1.5" of insulation. This creates a large solar mirror that reflects the sun into the gravel and floor, creating a 10 - 15,000 pound solar heat sink.
The exterior of the north wall is covered in corrugated aluminum siding.
