A greenhouse has a frame of standard PVC tubes and PVC fittings. A rectangular base frame supports a plurality of vertical tubes, which, in turn, support a rectangular gable-type roof frame. Some of the tube-to-fitting couplings are friction-fit connections, some are glued connections and others are quick connect/disconnect connections for rapid assembly and disassembly of the greenhouse. A poly cover includes a center portion which extends from the base frame over the vertical tubes and the gabled roof frame and is coupled thereto by quick-connect/disconnect retainers, and a pair of end portions are releasably connected to respective ends of the center portion by double-pull zippers having box and pin connectors for variable, regulated ventilation and complete removal of the end portions.
