Series 500 Tall High Tunnels

GrowSpan Series 500 Tall High Tunnels feature tall sidewalls, making them the perfect tunnel house for growers that need added clearance.

Producing tall crops has never been easier. This extra-tall tunnel house provides all the necessary clearance and ensures ample overhead space, so damaging heat can be kept away from delicate plants. The improved ventilation that this structure provides can be particularly beneficial to growers in hotter regions and can help operations achieve their highest-quality yields.

Complete ventilation is also obtainable with the customer’s choice of Roll-Up or Drop-Down sides. Sides can be opened or closed with minimal labor, because the “Twist-of-the-Wrist” Assembly allows just one grower to quickly ventilate or close the tunnel house. 

Utilizing a Series 500 High Tunnel allows growers to get their crops started earlier in the year. They can get to market faster and provide additional protection, ensuring crops aren’t lost to inclement weather.
