Frequently Asked Questions

How much does the Poly Arch cost?

The final price of any greenhouse varies from customer to customer and depends on their specific requirements. However, the Poly Arch is one of our most economical structures to build. It’s tough enough for Northern climates yet affordable for cost-conscious growers in southern regions.

Talk with our Sales team about whether a Poly Arch is right for you. They can provide you with pricing specifics based on the setup you need.

How do you vent the Poly Arch greenhouse?

The Poly Arch is ideal for mechanical ventilation but is often praised for its simple approach to passive ventilation. It features a unique vent design that provides maximum cooling and air circulation.

The bottom rail of the roof vent sits approximately 3 feet above the gutter. When fully open, the
edge of the roof vent rises higher than the ridge, allowing the warmest air to escape. The raised bottom rail also gives you the ability to vent rain, snow, or shine.

We offer optional vents or roll-ups for sidewalls and end walls, as well as optional rack-and-pinion double or single ridge vents.
