How to Fasten a Plastic Greenhouse Hoop

A plastic greenhouse hoop is inexpensive and an ideal material to construct a season-extending structure for the garden. PVC conduits are readily available as hoop material, and sheet plastic comes in all sizes to attach to the hoops. They can be set up over raised beds or in sections of a large, soil-level garden to protect a particularly tender crop, or one that's not quite ripe, from cooler temperatures of fall. In the spring, a greenhouse hoop allows for earlier planting by warming the soil and providing protection from a late frost.

6 rigid PVC conduits
10 lengths of rebar
Sledgehammer
Tape measure
scissors

Instructions

- 1
  Measure out the dimensions of the location for the plastic hoop structure--15 feet long and 4 feet wide is an easy beginner size.
- 2
  Pound rebar pieces into each corner and along the length at 3-foot intervals with the sledgehammer. The rebar should go into the ground far enough so it can't be wiggled back and forth. This is the foundation for the plastic conduit support of the shelter. Each piece of rebar should be 2 feet long and 3/8 inch in diameter.
- 3
  Place one end of the PVC plastic conduits over the rebar protruding above ground on one side. Press down firmly so the conduit end sinks into the dirt, with the rebar inside of it for rigid support. The plastic pipe for the hoop is now free standing straight into the air. Each PVC plastic conduit should be 1/2-inch diameter and 10 feet long.
- 4
  Grab the top end of the plastic hoop, bending it to the rebar on the opposite side. Insert this end over the rebar, once again pressing down firmly. The conduit has now become the plastic greenhouse hoop and is securely fastened to the ground.
