A Low Tunnel is a tunnel typically made from steel and covered in polythene, usually semi circular, square or elongated in shape and low in height. Temperature, Humidity and ventilation can be controlled by equipment fixed in the Low Tunnel or by manual opening and closing of vents. low tunnels are miniature structures producing greenhouse like effect. These tunnels facilitate the entrapment of carbon dioxide and humidity.Low tunnels are less expensive as compared to the High tunnels but crop yield is low. Soil preparation, spraying and picking is difficult in this type of tunnel. Cucumber, melons, watermelons, bitter gourds, squashes, and snake gourds etc. can be grown in this type of tunnels.
