Selecting A Greenhouse
Figuring Costs

The cost of building or buying a greenhouse varies tremendously. It could range from several hundred dollars for an unheated polyethylene greenhouse to $3,500 or more for a year-round, automated, heated structure. Northern climate growers should consider the cost of heating, while schools in southern climates need to be more concerned with ventilating and cooling.

The cost of materials for the actual structure—frame, glazing, doors, and vents—is only part of the equation. A greenhouse structure itself, in fact, may account for only 40 percent of the ultimate budget for the entire project.

Other significant expenses to account for include:

• preparing the site
• laying the foundation
• accessories (fans, benches, trays, potting soil, fertilizers, watering equipment, and shading)
• electricity, heat, and water supply
• installing automated timers for heat, water, or ventilation, if needed
• future re-glazing

When shopping for a greenhouse, always ask for written quotations, including shipping costs, for basic materials and accessories. Prepare a budget, and be sure your funding is in place before breaking ground. For more funding ideas, visit the Finding Support and Funds section.
