Overview

In cooler climates, it is desirable to extend your growing season, but many people do not have room for a full-size greenhouse to do this. Portable greenhouse tops are simple to build and use over raised beds. They can extend your growing season well through winter and into springtime.

Step 1

Measure the length and width of your garden. Measure from the outside edges so that your portable greenhouse top will be able to slide over the raised bed.

Step 2

Lay the PVC pipe on the ground, creating an outline of a box that is the same size as your raised garden bed. Measure the PVC pipe and trim the pieces with the hacksaw so the lengths match the measurements of your garden.

Step 3

Cut 3-inch sections from the ends of the PVC pipe that attach to the corner connectors, then reattach using the T-connectors. This will create an additional spot to attach PVC pipe at the ends to form hoops.

Step 4

Paint uncut 10-foot lengths of PVC pipe with PVC pipe glue. Attach one end to the T-connectors along one long side. Carefully pull the other end over the top to the opposite side and attach to the T-connectors. This should form a box-like frame with hoops over the top.

Step 5

Cover with greenhouse plastic. Attach at least 3 snap clamps for each hoop to hold plastic in place. Add more snap clamps in windy areas or if high winds are expected.
