The 42-foot diameter Growing Dome is our largest geodesic greenhouse kit and is ideal for growing a forest of plants, fruits, and vegetables.  This greenhouse features two doors with windows for easier access and includes two 115V electric cooling fans (solar upgrade optional) and two solar attic fans for optimal cross ventilation.  The 42-foot large geodesic greenhouse kit offers maximum space and efficiency at $29 / square foot to produce fresh, organic vegetables, herbs, fruits, and flowers year-round.


Don’t need all 1,385 square feet of gardening space?  The 33-foot diameter Growing Dome is about the same cost per square foot as the 42-foot diameter greenhouse kit. While not quite as large, it’s a sizable geodesic greenhouse that can grow fresh produce for 8-10 people.


Large Growing Dome greenhouse kits make ideal structures for horticulturalists, market gardeners, farm-to-table restaurants and community gardens to extend the growing season.  Larger schools also benefit from the increased teaching space and abundance of raised beds for all of their classes.  Urban gardens, reservations and other food deserts will benefit from the large growing space to alleviate food insecurity challenges, and have their fresh organic food grown locally year-round!  Learn about Taspen’s Cosmic Kitchen and how they use their 42-foot Growing Dome Greenhouse for their farm-to-table restaurant
