How To Cover A Greenhouse Frame With Plastic?

This guide outlines the process of installing greenhouse plastic on a greenhouse, including measuring the greenhouse’s length and width, cutting the plastic to the desired size, attaching it to the frame using staples or nails, and sealing the edges with duct tape. The video provides an inside and outside look of the installation process, and explains four primary methods for attaching greenhouse plastic to metal framing: Single Poly Lock Channel and Spring Wire (Double Channel Poly Lock).

To attach greenhouse plastic, unroll the plastic film lengthwise along the structure, ensuring the label is visible from inside. Secure the plastic to the wood frame using staples, nails, or greenhouse clips, ensuring it is taut and free of wrinkles. Tighten the plastic by setting the roll of plastic up on one end, folding ends and tying a knot around a nub, and running the wire.

One of the most common methods is using lock channels and spring wire, which involve securing the sheeting at each peak to square the plastic. For larger greenhouses, fasten ropes to the corners of the film and throw them over the greenhouse. Pull the plastic to secure it in place.
