Build a Geodesic Greenhouse in Your Backyard

More sunlight, stronger structure, and more grow space per dollar. Open-source greenhouse plans from $29.

Why Geodesic?

Maximum Sunlight

The dome shape captures light from every angle throughout the day. No dark corners, no shadow walls. Your plants get even light distribution all year round.

Wind and Snow Resistant

Geodesic structures are the strongest shape per pound of material. Rated for high winds and heavy snow loads where rectangular greenhouses collapse.

More Growing Space

Enclose the maximum volume with the minimum material. A 16-foot dome gives you more cubic feet of growing space than a 16-foot rectangular greenhouse.

Year-Round Growing

The thermal mass of the dome shape retains heat better than flat-walled structures. Extend your growing season by months in any climate zone.
