YES-2-Tech, part of a program called Youth Exploring Science (YES) at the Saint Louis Science Center, published an instructable about making geodesic greenhouses. They write:

Working and building the domes has been exciting, but also very beneficial. We traveled around St. Louis teaching kids and adults about the purpose and functions of the greenhouses. Also, we supervised the building of domes at different community centers. With a geodesic dome greenhouse, you can extend the growing season of your plants and protect them from the harsh weather outside.
