Greenhouse optimal layout6/5/2023 ![]() ![]() Free-standing greenhouses are generally less expensive to build, as site preparation and erection costs are less.Ħ. Individual greenhouses can also be shut down when not in use. A separate growing environment can be provided in each house. It is easy to build additional greenhouses as more space is needed. The free-standing design is usually the best choice for the small grower planning on less than 10,000 square feet of growing space. A-frame design is standard when glass will be used for glazing. Gothic designs are the most popular as they provide higher light transmission and shed snow more easily. A free-standing greenhouse can have a quonset (hoop), Gothic or gable roof shape. Fuel supply, electricity, water service and headhouse layout should be sized with expansion in mind. Greenhouses are large, modular erector sets, and expansion is easy if planned in advance. It is best to create the plan on paper so that several alternatives can be evaluated. Expansion space should be planned for all areas. If commission membership and sentiments change, the expansion phases are already on file.Ĥ. This then becomes part of the approval process. You should submit the master plan with the initial phase of any multiphase build-out or expansion. A master plan can also help in obtaining zoning, wetlands and building permits. Conveyors, carts and pallet trays have advantages and disadvantages that you should evaluate.ģ. The selection of a plant-moving system is important in relation to the plants grown, distance moved and elevation differences. Typically, a headhouse makes up 10 percent to 20 percent of the total greenhouse space.Ģ. A headhouse is the key nerve center that houses the work area, office, germination and growth rooms, utility area, processing, shipping and storage. Because materials handling is one of the largest costs in a greenhouse operation, major consideration should be given to placement of a new greenhouse and its relation to the headhouse. Start with a facilities master plan that looks at topography and drainage, the building locations, parking for customers and staff, access for vehicles and equipment, and utilities (including water supply and electricity). Planning should be your first step in developing a framework for an orderly greenhouse build-out. However, there are many important design elements you need to consider once you have developed a business plan and selected a site. Greenhouses are becoming popular structural options for cannabis production due to lower facilities costs, easy expansion potential, ability to capture more uniform light from the sun and reduced production costs, as compared to indoor warehouse facilities. ![]()
