1 mil plastic with 3/8" holes 4.5" apart
Low tunnels are ideal for the early production of many vegetable crops. They are constructed by installing 6-foot wide sheets of punched plastic over wire hoops that are spaced about 4-5 feet apart. The cover is pulled taut over the hoops, and the edges of the cover are secured with soil. Generally, the cover is left over the plants for 3-4 weeks. The holes provide daytime ventilation, eliminating the need for manual venting. Low tunnels are generally used in conjunction with black plastic mulch for weed control and enhanced soil warming. Punched covers are warmer than slitted covers and have 3/8" holes positioned 4.5" apart for ventilation.
