A great selection of inexpensive greenhouse ideas that are inspired by simple housing structures. Time to swap out the canvas on my tipi for greenhouse plastic.
If you build a greenhouse, be sure it is -very- well anchored to the ground to resist high winds.
Years ago we had a home-built greenhouse that was very productive, but one day it got picked up by the wind and ended up a shattered mess in the neighbour's field. Not a good experience!
