If you have been wondering how to build a PVC greenhouse, rest assured that you can easily build one at a reasonable cost. One of the most types of greenhouses, it is much preferred for its affordability, functionality, and ease of setting up. You have to get down to some hands-on activity if you really want to learn how to build a PVC greenhouse.
You can build a PVC greenhouse with rebars that are driven into the ground at equal distances to act as the anchors for the ribs. You can directly drive the PVC into the ground and then stabilize the structure by attaching a wooden support all along the lengths. Another good way is to use wooden boards to make the base with and then attach the PVC ribs to these.
Begin by clearing and leveling the site. Drive four wooden stakes into the ground at the four corners of your proposed site. Now, use treated lumber and lay the board out on the four sides of the perimeter. Secure the boards to the stakes to get a squared out base.
With your base ready, you now have to put up the PVC ribs by attaching these at the base with the wooden boards using EMT (Electric Metallic Tubing) clamps. Space the ribs at an equal distance. If you are planning a small greenhouse space them at a distance of two feet. For the central ridge on the roof, you would need to drill holes in the ribs and the central pipe that connects them all at the points of contact and use tie wraps to secure the ribs with the ridge line. Alternately, you can carefully cut the central pipe into equal sizes pieces, reattach them to each other with PVC crosses and then attach the ribs to the crosses once the roof ridge is in place.
When the ribs are in place, you can construct the end walls. Make a door at one end. For additional strength, attach a diagonal wooden piece that runs from the base of the outer rib to the top of the hoop house in such a way as to angle across the corner of the top of the door. Repeat the same on the other side of the door frame. Repeat the process for the opposite end wall without installing the door.
Stretch the poly film over the structure and secure with staples and clips. Seal all gaps and secure at the base.
If you are still not too confident about how to build a PVC greenhouse, do some more research to be better informed, talk to owners of such greenhouses if you get the chance, surf the net, read relevant books or talk to your local hardware supplier. All the information you gather will equip you to choose the right size and material with appropriate specifications.
