| The low tunnel is a small, portable green house placed over short, row crops.The Climax polyethylene are resistant to puncture, rodents and micro-organisms. Clear Slitted Row Cover Low tunnels are ideal for the early production of many vegetable crops. They are constructed by installing 6-foot wide sheets of either slitted or perforated plastic over wire hoops that are spaced about 4 feet apart. To prevent wind damage, the cover is pulled taut over the hoops and the edges are secured with soil. Generally, the cover is left over the plants for 3-4 weeks. The slits and perforations provide daytime ventilation, eliminating the need for manual venting. Frost protection of 2 to 4 degrees F is afforded by the covers, but the biggest benefit is growth enhancement provided by the daily increments of solar heating. |
