Planning and Building a Greenhouse
Adapted from Fact Sheet 645 - University of Maryland Cooperative Extension Service, David S. Ross, Extension Agricultural Engineer, Department of Agricultural Engineering Careful planning is important before a home greenhouse project is started. Location The greenhouse should be located where it gets maximum sunlight. Deciduous trees, such as maple and oak, can effectively shade the greenhouse from the intense late afternoon summer sun; however, they should not shade the greenhouse in the morning. Good drainage is another requirement for the site. Types of Greenhouses A home greenhouse can be attached to a house or garage, or it can be a freestanding structure. Attached Greenhouses Lean-to. Even-span. Window-mounted. Freestanding Structures Freestanding greenhouses are separate structures; they can be set apart from other buildings to get more sun and can be made as large or small as desired (Figure 2C). Structural Materials Frames Quonset. Gothic. Rigid-frame. Post and rafter and A-frame.
