Greenhouses are structures covered with a transparent material that allows sufficient sunlight to enter for the purpose of growing and maintaining plants. Greenhouse range refers to two or more greenhouses located together. Headhouse is a central building used for offices, storage and work space with attached greenhouses. See Figure 13.1.
