How to cover a greenhouse with plastic

Covering a greenhouse with plastic involves several steps to ensure proper installation and functionality. Here is a general guide on how to cover a greenhouse with plastic:

Materials and Tools:

  1. UV-resistant greenhouse plastic sheeting
  2. Batten tape or base wire
  3. Spring wire or lock channel
  4. Polyethylene clips or snap clamps
  5. Screwdriver or drill
  6. Utility knife or scissors
  7. Measuring tape


  1. Prepare the Greenhouse Frame:
    • Ensure that the greenhouse frame is stable and securely anchored to the ground.
    • Remove any debris or obstacles from the frame.
  2. Measure and Cut Plastic Sheeting:
    • Measure the dimensions of the greenhouse frame, ensuring enough overhang for securing the plastic.
    • Cut the greenhouse plastic sheeting to match the dimensions, leaving extra material for securing.
  3. Attach Batten Tape or Base Wire:
    • Secure batten tape or base wire around the base of the greenhouse frame. This provides a secure foundation for attaching the plastic.
  4. Secure Plastic Sheeting to One End:
    • Start at one end of the greenhouse and secure the plastic sheeting to the frame using polyethylene clips or other suitable fasteners.
    • Pull the plastic tight and attach it to the frame along one side.
  5. Stretch and Secure Plastic Across the Frame:
    • Carefully stretch the plastic sheeting across the greenhouse frame.
    • Secure the plastic to the opposite side of the frame, ensuring it is taut and without wrinkles.
  6. Secure Plastic to Remaining Sides:
    • Secure the plastic along the remaining sides of the greenhouse frame, pulling it tight to avoid sagging.
    • Use clips or fasteners to secure the plastic at regular intervals.
  7. Attach Spring Wire or Lock Channel:
    • Install spring wire or lock channel to secure the plastic along the sides and top of the greenhouse frame. This helps to hold the plastic firmly in place.
  8. Trim Excess Plastic:
    • Trim any excess plastic using a utility knife or scissors.
    • Ensure that the edges are neat and tidy.
  9. Ventilation and Access Points:
    • Install ventilation and access points by leaving openings or adding roll-up sides, depending on the greenhouse design.
  10. Inspect and Make Adjustments:
    • Inspect the plastic covering for any tears, holes, or loose areas.
    • Make any necessary adjustments to ensure a secure and snug fit.

Remember that the specific steps may vary based on the design and type of greenhouse. It’s essential to use UV-resistant plastic to withstand prolonged exposure to sunlight without deteriorating. Additionally, follow the manufacturer’s guidelines for your specific greenhouse covering material and frame.
