Greenhouses for Sale in Minnesota

Minnesota buyers searching for a four-season, year-round, or all-season greenhouse usually want to know what they can keep growing after outdoor beds freeze. What that requires depends first on the crops. Spinach and kale can grow at lower temperatures than fruiting tomatoes or citrus, so the winter temperature and lighting plan may be very different.

A Growing Dome uses 16 mm five-wall polycarbonate, reflective insulation across the north side, and a water pond that absorbs warmth during sunny hours and releases some as the dome cools. The undersoil system circulates air through the perimeter-bed area. Account for these features before adding a heater or grow light.

For most Minnesota projects, begin with snow, cold, and winter light, but include summer heat and humidity in the same operating plan. Plan for ventilation, shade, and air movement.

Review the model-specific snow ratings and use the greenhouse climate calculator to compare configurations for a Minnesota ZIP code and crop plan.

The 26-foot is the most common standard model among Minnesota sites marked installed and active in our current records. The 22-foot and 33-foot models make up the three projects in fulfillment during 2026.

Start by sketching the pond, beds, paths, permanent plants, seed-starting area, and work space. A household vegetable garden, a school lab, and a farm project can use the same floor area very differently. With a larger size, you can separate those uses; with a smaller size, you will need tighter choices.

Compare all six sizes in the Growing Dome greenhouse guide, then check current models and pricing in the DIY Greenhouse Kits collection.

Some Minnesota growers will also consider a deep winter greenhouse. The approach documented by University of Minnesota Extension concentrates glazing toward the winter sun, uses an insulated opaque wall, and stores collected heat below ground. The layout is built around cold-season production.

A Growing Dome is a freestanding geodesic greenhouse with polycarbonate around the curved shell, reflective north-side insulation, a water pond for thermal mass, and internal air circulation. Plan the open interior for summer and winter crops, perennial plants, seed starting, and time spent in the garden.

Read the deep winter greenhouse comparison before deciding which structure fits the crop plan and the way you want to use the space.

Before ordering, ask the local building department which design snow load, wind criteria, frost-depth requirements, setbacks, and permit documents apply to the site. Use that information, along with grade, drainage, soil, and equipment access, to choose the greenhouse foundation.

Growing Dome kits ship by freight from Pagosa Springs, Colorado. Plan separately for delivery access, unloading, site preparation, foundation work, owner-supplied materials, and greenhouse assembly. Review current shipping information and installation options while building the project budget and schedule.
