Description Features & Benefits

High Tunnels are an increasingly popular trend for growers and a proven technology for crop production. The term high tunnel is a loosely defined phrase for growing fruits and vegetables in greenhouses, although some high tunnels are used for cut flower production. High tunnels may be used to extend the growing season by providing protection for early or late season production, or they may be used for year-round growing. High tunnels are becoming increasingly popular due to the low start-up cost and quick rate of return on investment.

  • Base Package
    The base package includes the framework complete with all pre-drilled steel, hardware and instructions. Each base package includes 2” x 4” end wall framing brackets; a double layer of 6 mil, 4-year, UV-treated poly for the roof and end walls; poly lock for the roof and end walls; and a pair of roll up side wall kits with a gear box for rolling up the sides. Every frame has 4’ bow spacing, wind bracing and is easy to assemble.
  • Door Option
    We have several good high tunnel door options.
  • Gable Shutters
    Gable Shutters located at each end of the greenhouse near the peak help alleviate hot air that may build up during the summer months or humidity that may build up in the winter months. Use 36" shutters with 18', 20' or 22' widths and use 48" shutter with 26' or 30' widths.
  • Steel End Wall Framing
    Metal end wall framing kits are available for $470 per end for the 18’ and 20’ widths, $600 for the 22' and 26' widths, and $680 for the 30' widths. These are recommended when using polycarb for end walls.
  • Polycarbonate End Walls
    Polycarbonate end walls include all 8 mm clear polycarbonate warranted for 10 years, all aluminum extrusions and necessary hardware.
