Retail prices from before taxes from Lowes in Las Cruces, NM. Local sales tax may need to be added.
From the manufacturer: Solaroof 172- designed for all types of cultivation. Made from high quality coated woven
poly to the highest standards. Extra-strength (3,500 lb/yd) makes it hail and tear resistant. Unique additives blocks
harmful UV light and reduces the spread of fungal diseases (botrytis) and deters insets (aphids) from entering the
greenhouse. Anti-drip prevents droplets from falling onto plants. Excellent diffusion improves light transmission
and eliminates shadows. Infrared additives keep temperature higher during cold nights.
