High tunnels, also called high hoops or hoop houses, are temporary structures that extend the growing season. These covered structures are constructed in the field in order to protect crops from the weather (rain, wind, cool or warm temperatures) and, in some cases, pests. High tunnels offer an intermediate level of environmental control—a growing system between row covers and greenhouses. In comparison to greenhouses, they are unheated, provide less climate control, and are less expensive. This article lists publications and videos on high tunnel construction.
The most important issues to consider before constructing a high tunnel are:
- Purpose of the tunnel in the farming system
- Budget available
Once these issues have been addressed, the next step is to learn about the diverse designs and materials available and select those that best fit the purpose, budget, and location.
