    The cost of a typical polytunnel greenhouse can vary quite a bit depending on several factors, but here are some general guidelines:

    1. 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.
    2. 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.
    3. 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.
    4. 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.
    5. 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.
