Greenhouses for Sale
A Growing Dome is a greenhouse kit for extended-season and year-round plans. We have built the kits in Pagosa Springs, Colorado, for more than 35 years, and more than 3,000 now stand in all 50 states and 16 countries. That range has taught us to start with the site and what the gardener wants to grow.
Six sizes, from 15 to 42 feet, cover small backyard gardens as well as larger shared or commercial projects. Kits start around $12,000. The final project cost also reflects the foundation, freight, installation, and climate or engineering options selected for the site.

How Growing Dome systems support year-round growing
A Growing Dome combines a geodesic frame, 16 mm five-wall polycarbonate glazing, a water pond for thermal mass, and ventilation. The frame distributes loads through interconnected triangles; the pond absorbs warmth during sunny hours and releases some as the greenhouse cools.
The 15-, 18-, 22-, and 26-foot kits use heat-activated vents. The 33- and 42-foot domes use powered fans. For year-round growing, start with crops that suit the season, then plan supplemental heat, light, and airflow based on your climate and temperature goals.
Explore passive solar design, thermal mass, the undersoil system, and automated vents. For model-specific wind and snow ratings, use the weather resistant greenhouse kit page.
A modified 26-foot dome in Haines
Mardell and Diz grew tomatoes from spring into fall in their modified 26-foot dome in Haines, Alaska. They adapted it to their snowy coastal site with a center support, covered entry, extra vents, and concrete beds for thermal mass.

A cold winter at Rodale Institute
At the Shumei garden at Rodale Institute, a seven-year-old 22-foot Growing Dome went through below-zero winter weather without a heater. With heavy straw mulch over the beds, the interior stayed just below freezing and hardy greens and herbs survived.

Choosing a Growing Dome size
Sketch the beds, paths, pond, and working room before choosing a diameter. The six models run from 15 to 42 feet, and local wind or snow requirements can narrow the choice. Use the greenhouse guide to compare dimensions and systems, browse current pricing in the shop, or use our comparison pages to see how the Growing Dome differs from other greenhouse types, including the gothic arch.
