High tunnels, or hoophouses, are unheated greenhouses that can help market gardeners extend their growing season so that they can improve the profitability of their farms. This website is part of a USDA-sponsored project that is testing and promoting high tunnel systems in the Central Great Plains.
We hope to provide information developed under our project, and links to relevant sites around the world, so that growers and educators have a one-stop source where they can find information on all aspects of high tunnel construction and use.
