ABSTRACT:
There is disclosed a flexible-walled demountable greenhouse in which the support structure consists of a plurality of rods, for example 6, extending from the periphery of the base to a cap structure at the top central portion of the greenhouse; the rods are of fiberglass or other strong, light material and are keyed at one end to lock into the cap structure. The walls are preferably a double thickness of plastic such as polyvinyl chloride or polyethylene having vertically extending seams to form sleeves in which the support rods are placed. The base of the support rods are engaged in nylon cup and anchor loops which may be anchored to the ground by stakes so that no floor or foundation is required. A zipper closured door is provided in the walls.
