The Growing Dome® comes with a 5-year warranty by Growing Spaces® against structural failure of the Growing Dome® struts and hubs, given regular maintenance. The structural warranty does not include the foundation. The polycarbonate greenhouse glazing is warrantied by the manufacturer against hail damage and yellowing (pro-rated for 10 years). Growing Spaces® shall pass on all warranties for other parts of the Growing Dome® from the manufacturer to the Purchaser. Warranties will be considered void if the Purchaser alters the design of the Growing Dome® or its features and/or if the Growing Dome® is used for a purpose other than a greenhouse. Our Warrant is documented on our Product Terms and Conditions.
