Our Growing Domes are capable of growing food year-round in most climates of the United States, without additional heating systems, even in the heart of winter.
Furthermore, given the amount of insulation, thermal mass, and the inherent energy efficiency of its geodesic shape, it requires a third less energy than a traditional greenhouse. It can withstand winter temperatures down to zero outside, while not freezing inside.
Winter gardening in your Growing Dome greenhouse is an amazing experience. Walking in your dome from the dormant vegetation outside into a thriving garden is both uplifting and relaxing.
The ability to grow fresh produce year-round is a major benefit of the Growing Dome geodesic greenhouse kit. Winter greenhouse gardening is possible without supplemental heat in most northern climates, which empowers you to have more control over your food sources.
