Our 22-foot Growing Dome geodesic greenhouse kits are ideal for medium to large families wanting to control their own food source.  Greenhouse kits from Growing Spaces provide the optimal environment for growing fresh, organic vegetables, herbs, fruits and flowers using solar energy.  The additional height of the 22-foot greenhouse allows you to grow grapes, figs, and dwarf citrus trees up high with lots of room for everything else below canopy.   Small farmers and growers also use the 380 square feet of growing space to sell vegetables at farmer’s markets or farm stands.  All geodesic Growing Dome greenhouses feature heat-activated automatic opening vents and an above-ground pond to stabilize temperatures year-round.


If you are interested in a smaller Growing Dome, view the 18-foot diameter greenhouse kit, or if you’d like extra space for a patio table or lounge chairs view our 26-foot diameter Growing Dome with 530 square feet of gardening space.  Laura and Dwayne don’t have good quality produce at their local stores in Wrangell, Alaska, and use their 22-foot Growing dome to harvest fresh food in their Alaska greenhouse.
