Details

The 18-foot diameter Growing Dome geodesic greenhouse kit is a wonderful way for small families and urban growers to enjoy a healthy, sustainable lifestyle.

Its strong design resists harsh weather, maximizes light, and regulates temperature. Built with quality materials for lasting performance, it's customizable for any climate. While the geodesic design may seem complex, all of our Growing Dome kits are designed for DIY assembly. Each kit comes with comprehensive, step-by-step instructions, including video tutorials, and all the necessary hardware. Many of our customers successfully assemble their Growing Domes themselves using the provided guidance. We also offer installation options and customer support to answer any questions you may have during the assembly process.

At 255sq.ft. with a height of 10ft. 8in., it has 80 more square feet than our smallest greenhouse kit , the 15-foot diameter Growing Dome.

Our next biggest size is the 22-foot diameter Growing Dome which has a total of 380 square feet of greenhouse gardening space! Learn about how our friend Andrew Trujillo makes the most out of his 18′ Growing Dome to supply food for his wife and three young kids while also volunteering at the Pine River Garden Club .
