I’ve been reading about greenhouses constructed of, e.g., 20’ lengths of #4 (1/2") rebar, where the main structure is made up of the rebar bent so that both ends are in/at the ground (and the gradual bend makes up the greenhouse).
Not this big, but that’s the idea:
Bob's Projects & Ideas: Rebar Greenhouse ~ Northern Greenhouse (hope this link is ok, it’s not amazon, but they don’t compete with ILGM)
Was thinking I could use ~3 pieces of rebar hoops, plus some rebar for bracing, plus a covering… and somehow, door(s).
