While most people know a greenhouse is used to grow plants, many don't understand the benefits that go with using a greenhouse. A greenhouse can help in regulating temperature, humidity, and water distribution, all of which can promote and encourage good plant health and lead to maximum production. Whether you are a serious gardener, practicing at home, or have plans to run a plant nursery for profit, a greenhouse can offer convenience and increased productivity .
You can also regulate the amount of water your plants receive, so drought and flood are rarely an issue. The allure of the greenhouse is often the fact that you can extend your growing season. This is especially desirable in cooler, northern climates where the growing season lasts only a few months, not nearly long enough for some vegetables to be harvested.
A greenhouse works by the sunlight entering through the windows and resulting in energy and heat which is trapped inside. Your plants then benefit from the light and the warmth of the greenhouse. Most greenhouses also include some sort of opening window or fan to help keep the heat from becoming hot. Because the greenhouse is enclosed, the heat remains inside overnight, continuing to keep the plants warm and helping them to grow.
Coming in a wide variety of shapes and sizes, greenhouses can be made from a multitude of materials; anything from old windows to PVC pipes to metal frames using plastic or glass to cover openings. When cost becomes a factor, there are plans available to build your own, as well as greenhouse kits with all materials shipped together with instructions to construct the greenhouse over a weekend. Even cheaper still, some opt for a simple ground covering of curved pipes draped with clear plastic. When put together correctly your greenhouse shouldn't need further care, leaving you time to tend to your plants. Benches, shelves, and even washtub-style sinks can be installed inside a large greenhouse, maximizing your growing space and making cleaning up easier.
If you choose to grow plants or your own fruits and vegetables, the benefits to a greenhouse are more than just the beauty of a fresh bloom or the first bite of home-grown produce. A greenhouse keeps out several garden pests, such as raccoons, dogs, cats, rabbits and deer that often cause trouble digging up plants, eating flowers and eating your food before you get a chance to. You also have the opportunity to grow organically or at least know what kinds of chemicals have been used on your plants. Another benefit is the ability to start seeds earlier in the season under a controlled environment without fear of losing a whole crop when something unexpected happens outside. If you enjoy it enough, you may consider selling produce or potted plants as an additional source of income because your plant growth results are healthier, stronger and more reliable in greenhouses.
