You can't control the weather, but you can have all-weather control of your greenhouse with our complete roll-up curtain system. Our system includes everything you will need for years of continuous operation. No lumber to purchase, no extra poly fasteners to purchase, our price includes everything. In addition, you can choose a manual crank or an incrementally automatic system. Our fabric is a heavy-duty 14 mil. coated 10x10 weave fabric (not 6 mil. poly) strong enough to withstand the abuse of windy condition and even rocks thrown by lawn mowers and weed-eaters. Growers prefer curtains that roll up from the middle as opposed to rolling up from the bottom; crank rotations are reduced by 50% and curtains are kept straight. Affordable and easy to operate natural ventilation as well as adaptable to any greenhouse with straight sidewalls.

Base Wall Advantages:

• PROTECTS plants from wind and cool air when open.
• REDUCES crank rotations by as much as 50%.
• PREVENTS snow from piling against curtain.

NOTE: Generally a 60/40 ratio is recommended (60% curtain opening, 40% base wall).
