If you plan to build a commercial cannabis greenhouse, you’ll need to consider the costs involved. These include framing, a heating and cooling system, insulation, irrigation and grow lights, and a CO2 generator. The cost of these components will vary depending on the size of your greenhouse and how you compartmentalize it. Generally, the price per square foot will be between $25 and $50.
The construction material you choose will greatly affect the overall cost of the greenhouse. Materials such as steel and aluminum are generally more expensive than other materials. Steel, for example, will last longer than aluminum and is more versatile. It can also be formed into various shapes. Steel is also best for humid planting zones.
A 10000 square-foot greenhouse requires approximately 220,000 gallons of water over 10 months, half of which is used for fertigation, a process of applying fertilizers to the soil. Municipal water costs about $0.153 per gallon, so the total cost for water and fertilizers is around $0.321 per square foot over 10 months. You’ll also need to purchase pre-mixed fertilizers, which increase the cost.
Once you have decided on the size and materials of your greenhouse, you can begin the process of choosing the materials. You can also look for recycled materials to reduce your greenhouse cost. Recycling materials can include gravel fill, concrete pavers, and plastic sheeting. Inquire about the materials used for greenhouse construction and ask contractors about their experience. Also, ask about their licensing, insurance, and references.
