Greenhouses for Sale in Alaska
More than 30 Growing Domes stand across Alaska, from Haines to Nikolski on Umnak Island. Every kit begins at our Pagosa Springs, Colorado, factory, where we have built Growing Domes for more than 35 years.
For Nikolski, that meant four large crates and a crew traveling to the Bering Sea to build two 33-foot domes for one of Alaska's most remote communities.

Six Growing Dome sizes for Alaska sites
Local snow and wind requirements narrow the dome and foundation options; freight access, winter light, and crop goals shape the rest of the project.
Snow, wind, and winter light in an Alaska greenhouse
A greenhouse in Haines faces wet coastal snow; farther north, the winter light window keeps shrinking. One Haines owner reported nearly six feet of wet snow on a modified 26-foot dome with a center support pole and covered entry.
Winter light changes what supplemental heat can accomplish. A household may choose a concentrated summer season, as the Haines owners did, while a school or community program may need a longer calendar. We can compare that goal with the model-specific snow and wind requirements for the project.
For a closer look, explore passive solar design, thermal mass, the undersoil system, and automated vents. The weather resistant greenhouse kit page lists current snow and wind capacities by size and foundation.

Two domes in the middle of the Bering Sea
Our crew helped build two 33-foot Growing Domes in Nikolski, an Unangan community on Umnak Island in the Bering Sea. Four large crates made the trip to the remote site, where the domes were assembled to extend the local growing season in a village with nearly 4,000 years of history.

A village build in New Stuyahok
With help from our team, the Yup'ik community of New Stuyahok built a 33-foot Growing Dome beside Chief Ivan Blunka School. The planned uses included starting seedlings, teaching organic gardening, and bringing multiple generations together in the garden.

Summer tomatoes, winter snow in Haines
Mardell and Diz replaced their hoop houses with a 26-foot Growing Dome and grew tomatoes and other warm-season crops during the bright Haines summer. For their snowy, humid site, they added a center support pole, a covered entry, and concrete beds for thermal mass, and built the dome without a pond. They later reported nearly six feet of wet snow on the dome. Their season ran from late May through October, with the dome resting during the darkest winter months.

Growing Dome sizes for Alaska homes and shared projects
All six Growing Dome sizes appear in Alaska, with the 18- and 33-foot models tied as the most common. Nikolski and New Stuyahok chose 33-foot domes for shared community uses, while the Haines owners grew seasonally in a modified 26-foot. We can compare sizes based on who will use the greenhouse, what should keep growing during the darkest months, and whether remote access limits the scale of the project. The greenhouse guide compares the six models, the shop lists current products, and the comparison pages include a direct look at the gothic arch greenhouse.
A greenhouse season that works in Alaska
In Alaska, the useful season may be defined by light as much as temperature. Once you tell us how far into the year you hope to grow and who will use the dome, we can help with size, equipment, remote delivery, and installation.
Professional Growing Dome installation is available in Alaska for an additional cost. Compare installation options and review Pay Over Time with Affirm. For projects that include both the kit and professional installation, also review Greenhouse Project Financing with Salal Credit Union.
