A strict definition of a high tunnel does not exist, and the terminology may change depending on the structure’s use
- “Hoophouse” and “High Tunnel” are often used interchangeably
- For example, a market farmer might grow an additional crop of sunflowers in a “High Tunnel” after first frost, whereas a nurseryman could over winter container-grown perennials in the same structure but call it a “Cold Frame”
- The same structure is also marketed to livestock operations for animal, feed, and equipment shelter
Gutter Connected High Tunnel indicates that two or more bays are connected at the gutters
French Tunnel is the European term for a single-bay high tunnel
Spanish Tunnel is the European term for a multi-bay high tunnel
