A hoop house is a simple structure used in gardening and farming to extend the growing season. It consists of a series of curved metal or plastic hoops covered with a layer of clear plastic. This design allows sunlight to enter while trapping heat inside, creating a warmer environment for plants. Hoop houses are often used to grow vegetables, flowers, and other crops earlier in the spring and later into the fall. They provide protection from harsh weather conditions, pests, and diseases, making them a popular choice for both commercial growers and home gardeners.
