Tunnel structure
The GrowSpan Roll-Up Low Pro Tunnel uses an innovative, low profile design that allows the cover to easily retract into the peak of the roof with a simple twist of the wrist. Growers have the options of covering the tunnel with 6-mil clean greenhouse film or a 6-ounce black/silver cover, which provides light deprivation to control flowering cycles.
