The Round High Tunnel Kit is a durable, all-steel high tunnel greenhouse designed for growers who want to extend the growing season, protect crops, and create a reliable growing environment. Built with a heavy-duty steel frame, this high tunnel provides long-term strength and durability without the rot, warping, or maintenance concerns associated with wood structures.
The steel framing is 100% U.S.-made, with hoops and components cut, bent, and fabricated at our Texas facility. The hoops are constructed from USA-sourced 16-gauge steel tubing with a clear-coated galvanized finish, providing dependable performance and corrosion resistance in outdoor growing conditions. Some kit components, including greenhouse film and fasteners such as nuts and bolts, are sourced internationally.
Designed for both small-scale growers and larger homesteads, this steel high tunnel greenhouse kit provides the strength and interior space needed for productive growing. The round hoop design creates an efficient growing structure while helping protect plants from changing weather conditions and providing an enclosed environment for vegetables, flowers, herbs, seedlings, and other crops.
