Greenhouses for Sale in Oregon
More than 60 Growing Domes stand across Oregon, from the rain-soaked coast and western valleys to colder, drier country east of the Cascades. We have built the kits in Pagosa Springs, Colorado, for more than 35 years. For an Oregon site, one of our first questions is which side of the Cascades you are on.
On the central coast, Gabrielle and Urs kept tomatoes ripening through winter beside lemon and banana trees. Grow lights carried the garden through the darkest months.

Wet winters west, snowier winters east
West-side plans emphasize winter light and moisture; east-side sites add colder nights, dry summer heat, and local snow loads.
Oregon greenhouse choices west and east of the Cascades
West of the Cascades, limited winter light and persistent moisture shape the winter garden. East of the Cascades, colder nights and snow affect winter plans, while dry summer heat creates a different cooling challenge. The Growing Dome system is the same in both regions; crops, equipment, foundation, and structural requirements can differ.
On a gray western Oregon day, the glazing admits both direct and diffuse sunlight, and the pond absorbs some warmth while the sun reaches it. The undersoil fan circulates air through the growing area, while automatic vents on smaller kits or powered fans on larger domes release excess heat. Western Oregon projects often need more attention to humidity and winter lighting. East of the Cascades, summer cooling, cold protection, and higher snow-load configurations are more common concerns.

Winter tomatoes on the central coast
On the central Oregon coast, Gabrielle and Urs kept tomatoes ripening through winter in their 22-foot Growing Dome, with lemon and banana trees growing near the koi pond. Because November through January brought so little daylight, they supplemented the garden with grow lights.

A diversified farm near Ashland
Near Ashland, La Terra Vita used a 33-foot Growing Dome to propagate herbs and fruit trees at 4,700 feet. The dome was one part of a diversified community farm that also included an orchard, herb gardens, a mushroom barn, and beehives.

A school dome full of flowers in The Dalles
Students at Colonel Wright Elementary in The Dalles filled their 26-foot Growing Dome with flowers, then ate winter lunches among the blooms. Sales from the flowers helped fund other school projects.

Oregon winter moisture, freight, and local approval
Local permits, wet-season moisture, freight, and a realistic year-round crop plan.
The 26-foot is Oregon's most common Growing Dome size
The 26-foot is the most common model among Oregon's 64 installations, followed by the 18-foot. Oregon projects also show how differently the interior can be lived in: a coastal household grew lemons and bananas beside the pond, while students in The Dalles ate winter lunches among flowers. Growing areas, movement, work, and time shared inside all shape the layout. For scale, the greenhouse guide shows all six sizes; current pricing appears in the shop. The comparison pages include a direct comparison with a gothic arch greenhouse.
Growing through Oregon's wet and dark months
Winter tomatoes on the coast require a different approach from cool-season greens east of the Cascades. A useful first comparison starts with the crops and seasons you care about, not a finished property plan. We can then address light, moisture, freight, and installation choices when they become useful.
