DIY Greenhouse or Shed Frame - Use E-Z Frame plastic connectors to create a frame of inexpensive 2x2s from your lumberyard. Then, cover it with plastic sheets, panels, plywood, or whatever to create your inexpensive greenhouse or shed. The connectors add strength and simplify saw-cutting the 2x2s
The Behar Greenhouse is a model of passive solar sustainability. The frame is made of locally milled Black Locust timber. The in-bed thermal air exchange system and expandable end wall allow for tight control of temperature. The growing tables are suspended from overhead tracks that allow for more efficient use of space and the base vents give access into the cold frame along the base of the south wall to harden off young plants.
