High Tunnels Defined

High tunnels are simple structures used to extend the growing season for horticultural crops such as vegetables, small fruits, and cut flowers. While they resemble greenhouses, the structures are much more economical and less labor-intensive to construct. They consist of simple frames usually covered by a double poly layer. The sides roll up to vent excess heat. Most high tunnels are not heated nor do they require electricity to operate.

Community of Practice

Growing in high tunnels is different than growing outdoors or in a heated greenhouse. Recognizing that high tunnels present unique challenges to producers in the northern Great Plains and upper Midwest, we have formed this community of practice to share knowledge regarding construction issues, disease diagnosis, insect and mite management, fertility, and cultivar information.
