16' DIY High Tunnel Greenhouse Kit: Build Your Own Hoop House

Grow bigger, grow longer, grow better.

This DIY Greenhouse Kit gives you everything you need to build a professional-grade high tunnel greenhouse, minus the lumber you can source locally to save.

Standing approximately 9.5' at center, this kit is built for serious growers who want a durable, affordable growing season extension without the markup of a fully packaged kit.

What's Included:

• Spring lock wire and lock channel to secure your greenhouse plastic
• Ground post driver for safe, accurate post installation
• 1-3/8" x 1-3/8" cross connectors (arches to ridge poles)
• 4-year, 6 mil greenhouse plastic,  sized to cover the full structure including end walls
• All required screws, nuts, bolts, and connectors
• Instructions for the build
• Printable Buy Local Chart

What's NOT Included (and why): Lumber and 1-3/8" top rail are not included and that's intentional. Buying these locally can save you thousands of dollars. We've made it easy with our printable Buy Local Chart so you know exactly what to order and where.

Best lumber choices for moisture-exposed structures: redwood, cedar, or pressure-treated.
