Having the Perfect Greenhouse

Greenhouses are buildings made to grow vegetables, fruits, and flowers. They store heat that the sun produces and creates a warm setting for your plants. The buildings have glass or plastic walls and roof. The frame can be made of metal, wood, or plastic. Greenhouses come in a variety of sizes. They can also be built in many different locations.

The first greenhouses were built in Italy in the sixteenth century. The purpose of the greenhouse was to store exotic plants from around the world and keep them alive. An environment needed to be created in Italy that the plants were used to. Thanks to many of the trial and errors they experienced in the sixteenth century we are now able to have greenhouses. This idea soon spread around the world.

When choosing the size of your greenhouse, consider what your needs are. If it is for a hobby a smaller greenhouse close to the home would do fine. The more plants that you want to grow in the greenhouse the bigger the greenhouse you will need. Make sure your greenhouse has peak and eave height. Taller greenhouses are easier to maintain a constant temperature.

Build your greenhouse in an area that provides partial shade. A shade curtain can be purchased and used if shade is not available. Have the ends of the greenhouse running east and west. Your greenhouse should get at least six hours of direct sunlight daily. Avoid building your greenhouse in a location with a lot of wind.

Glass is not very commonly used in greenhouses in today’s society. Glass does not retain heat for long periods of time. You will need a very sturdy frame if you decide to use a glass covering. Also, use double or triple strength glass to avoid breakage. A glass greenhouse must be perfectly square to prevent air leaks. It might be more suitable to use a plastic covering. Plastic coverings come in fiberglass, acrylic sheets, polycarbonate, and polyethylene. Air leaks are not as common in plastic coverings because you don’t have to be as precise when using it. Also, larger sheets of plastic create fewer joints. The only downfall is that plastic coverings need to be replaced more often than glass.

Wood is a popular frame for hobby greenhouses because of the attractiveness. The rotting wood is a problem with wood framed greenhouses. Wood has the ability to retain water and moisture which will cause mold and rotting. Most commercial greenhouses are built with metal. It is best to have galvanized steel to prevent rusting. Metal is also cheaper and creates fewer shadows than wood. Plastic frames are most commonly used for hobby greenhouses. The lightweight of the plastic creates easy portability. Plastic is also low cost, but has the potential of creating more shadows. Plastic frames will need to be replaced after a few years of use due to the fact that the UV rays of the sun will cause the plastic to deteriorate.
