GrowSpan Roll-Up Low Pro Tunnels

The GrowSpan Roll-Up Low Pro Tunnel combines functionality with efficiency by providing natural ventilation, security or total darkness just by twisting your wrist.

• Economical option for protecting delicate plants, extending the growing season or controlling flowering cycles with blackout material.
• Cover quickly retracts to the peak with a twist of the wrist, providing maximum ventilation, and it can just as easily be deployed.
• Cover options include 6 oz. black/silver cover for blackout purposes or 6 mil clear greenhouse film.
• Frames are constructed with 14-gauge, USA-made, triple-galvanized structural steel tubing. 20'W and 26'W tunnels use 1.66" OD pipe. 30'W tunnels use 1.90" OD pipe.
• 32" clearance on the sides, 5' peak and 4' rafter spacing.
• End panels are included and feature a zippered section that allows equipment to be easily brought in and out of the tunnel.
• Heavy-duty ground posts included.
