How to build your own greenhouse.

How to build your own greenhouse.While building your own greenhouse is a significant amount of work, its still doable and a cheaper alternative.Once you've selected a suitable space and the dimensions of the greenhouse, you have to decide what to build it out of. There are several choices, depending on your budget, your needs, and your skill-set. Strong greenhouses are built using galvanized steel, aluminum, or wood framing. Wood is probably the most familiar, and constructing a greenhouse from standard lumber is much like building any other structure. Of course, the wood will be subjected to high humidity on the interior, and constant sun exposure on the outside, so use pressure treated lumber and paint or seal it properly. Aluminum can be fitted together similar to wood and is lighter and more durable, but it is also more expensive. Steel is the strongest, most durable option, but it is also the most expensive and requires knowledge of welding and other metalworking skills. Although a less expensive alternative, plastic (PVC) pipes often can't provide the structural strength to stand up against wind and snow loads. Coverings There are a wide range of possible covering materials including glass, rigid fiberglass (plexiglass), double wall plastics, or plastic film. continue
