Greenhouses are a form of indoor gardening. They work by helping to keep out a lot of the harmful environmental things we don't want like hard rains, hard winds, or temperature fluctuations. In the summertime you can have greenhouses where you have all doors open and have fans moving air. In the wintertime, the opposite is going to happen. When the sunlight hits the greenhouse, it warms it up. The greenhouse also helps to keep humidity fairly high and carbon dioxide trapped inside the greenhouse. Plants use carbon dioxide and they release oxygen. It is important to always have fresh air coming through a greenhouse.
Some people grow their entire crop in a greenhouse, while some use it to start plants before moving them outside. You can get an early start on Spring this way. There are now a lot of lightweight greenhouses, which you place on top of your garden bed. It conserves the plants early and then can be disassembled and put away. You can also use it to protect crops in the wintertime.
A greenhouse has thousands of different uses. There are commercial units available, but it's typically not very hard to make your own using a wooden frame or PVC pipe. Using a clear plastic sheeting makes a good temporary greenhouse.
