The unheated greenhouse, or high tunnel, offers a vertical production environment suitable for crops such as indeterminate tomatoes and cucumbers. As it is a soil based system however, and passively heated, greenhouse cucumbers must be transplanted later in the spring than tomatoes, due to their intolerance for low root zone temperatures. However, cucumbers can provide good returns when grown in a high tunnel, given consistent pest control and matching variety performance with market demand. A variety trial of four greenhouse cucumbers was established in a cooperating high tunnel in the spring of 2011.
