Frequently Asked Questions

How does the 8x24 compare to the 8x20? It adds 20 percent more growing space and a sixth roof vent with the same frame and included kits. It is the definitive pick for growers who will use every square foot.

Which anchor option do I need? Wood for decks or timber bases, Concrete for slabs and patios, Dirt for soil or grass installs. The included steel base works with all three.

Can I use it year-round? Yes. The twin-wall panels retain heat in cooler months, and six roof vents manage summer heat across the long span. Add a small heater for frost protection in cold climates.

How hard is assembly? Components are pre-cut and labeled with hardware and tools included. Plan two full days with a helper for this size.
