The 18-foot Growing Dome geodesic greenhouse kit is a wonderful way for small families to enjoy a healthy, sustainable lifestyle. This kit is an ideal size for producing organic fruits and vegetables for your family of 3-4. It has a small footprint and is also great for urban gardening. All of our greenhouse kits are available with optional weather upgrades for desert climates and windy environments. Some of the polycarbonate triangles on the 18′ Growing Dome have taped tips to reduce waste and maintain affordability.
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 (@cogreenthumbdaddy) 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.
