The cost of a typical polytunnel greenhouse can vary quite a bit depending on several factors, but here are some general guidelines:
-
Size:
- The most significant factor in the cost is the size of the polytunnel. Larger polytunnels will be more expensive than smaller ones.
- A basic, small polytunnel (around 6ft x 8ft) may cost between $500 - $1,000.
- Medium-sized polytunnels (around 10ft x 15ft) typically range from $1,000 - $2,500.
- Larger commercial or industrial polytunnels (20ft x 40ft or larger) can cost $3,000 - $10,000 or more.
-
Materials:
- The quality and type of the plastic/polythene sheeting used can affect the cost. Thicker, more durable sheeting will be more expensive.
- The frame material (aluminum, galvanized steel, etc.) also impacts the price, with metal frames being more costly than plastic.
-
Features and Accessories:
- Additional features like automatic vents, heaters, cooling systems, and grow beds/shelving can add significantly to the overall cost.
- Customizations, such as bespoke sizes or shapes, will also increase the price.
-
Installation:
- Professional installation by a greenhouse specialist can add $500 - $2,000 or more to the total cost, depending on the size and complexity of the polytunnel.
- DIY installation can save a significant amount, but requires more time and effort.
-
Location:
- The cost may vary depending on the region and local market conditions. Prices tend to be higher in urban or high-demand areas.
On average, a mid-sized, basic polytunnel greenhouse (10ft x 15ft) with standard features can cost between $1,500 - $3,000 for the kit and professional installation. However, budgets can range widely based on the specific needs and requirements of your vertical gardening setup.
