Tunnels can be constructed with a material like polyethylene that warms the interior and prevents damage from cold or frost. The heights of the tunnels are generally close to the heights of the plants they are protecting.
  • Cloches for enclosing a single plant or a small group of plants are classified in group A01G 13/26. The heights of the cloches are generally close to the heights of the plants they are protecting.

Greenhouses can have the same rounded or semicircular shape as tunnels, but should be classified in group A01G 9/14. Tunnels are specifically designed for covering a row or rows of plants, and the tunnel width required to cover only a single row or small number of rows generally results in a structure much closer in height to that of the plants being covered. Greenhouses, e.g. high tunnels, are constructed in a size allowing a person to enter, independent of the configuration or size of the plants within.
