Greenhouses have been around since biblical times. People used to build these buildings and serve as homes. Nowadays, there are different types of greenhouses, most of which are made of metal. The metal that is usually used is galvanized iron; because it resists corrosion and is relatively inexpensive. These buildings can be constructed easily, and a handful of them can easily serve as an outdoor vacation home or a small business office.
Greenhouses now-a-days also play a role for herb gardening, and indoor vegetable production. Greenhouses help grow plants by capturing and changing sunlight, thereby transforming light energy to the energy required for plant growth. Many plants require lots of sunlight to grow well. Greenhouses transform the natural light, and trap the sunlight inside the greenhouse. This allows light to pass through the plants’ leaves and penetrate their roots and stems, growing the plants well even in winter.
Greenhouses can be used for indoor growing of vegetables. Under the right conditions, they can provide artificial sunlight, artificial warmth and humidity needed by some plants to grow well. Greenhouses can be designed to serve many purposes; for example, to capture and store heat generated during the summer, and to allow some plants to go through cold seasons. The most common types of greenhouses are those that provide heat and light, or heat and lighting, to a specific area. However, a greenhouse can be built to provide all three kinds of benefits, i.e. to capture heat and light, to provide artificial sunlight and humidity, and to grow various types of plants (even weeds).
Greenhouses now-a-days can be built with a combination of cooling and heating system. These days gardeners prefer to use the cooling and heating systems separately. However, the best thing about Greenhouse is that they can combine these three systems into one single one and make gardening easier than it ever was before. They have now become popular among gardeners all over the world. Greenhouse has also become one of the most common fixtures being installed at almost every house.
Heat and Humidity Greenhouses create a controlled environment for plants, giving them a chance to thrive and grow. Greenhouses are generally heated with electricity or natural gas, and some even use solar power as a source of heat and light. They allow plants to grow healthy and beautiful, without any pollution and stress from high temperatures. Some plants do really well in heat, while others need extra moisture and humidity to survive.
Ventilation Greenhouse works great for providing a controlled environment for plants. Nowadays greenhouses use vents, and windows are used to keep air and moisture inside the greenhouses. Greenhouses can also have vents facing different directions to allow proper ventilation. Greenhouses, especially large greenhouses, sometimes use fans to circulate wind more evenly and prevent drastic temperature changes.
