Greenhouse Building Instructions

Pound the six rebar stakes halfway into the ground in two rows of three, with five feet in between each stake. The stakes should be aligned in three pairs of two, equally spaced. This will produce a greenhouse that is 5 feet wide by 10 feet long, although the dimensions easily can be changed to fit the needs of your space by increasing or decreasing the sizes of the materials.

Set the end of a PVC pipe onto a rebar stake and bend it over so that it slides onto the corresponding stake in the next row. Repeat this process for all three pairs of stakes so that you have built a tunnel of bent PVC pipes.

Stretch the plastic sheeting over the PVC pipes. Attach the sheeting to the pipes all along each pipe using the zip ties, which are poked through holes made with the screwdriver or awl. Before making each hole, place a piece of clear plastic packing tape to strengthen the area, and then seal the hole with another piece of tape after the zip tie has been passed through the hole and around the pipe. Secure the sheeting all along the perimeter of the pipes.

Overlap extra sheeting on the ends of the greenhouse to serve as doors, which you can secure with Velcro or rope if you desire. Secure the bottom of the plastic sheeting to the ground with tent stakes if you wish.
