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 4-6 feet apart. To prevent wind damage, the cover is pulled taut over the hoops (but not stretched), 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. Low tunnels are generally used in conjunction with black plastic mulch for weed control and enhanced soil temperature.

Frost protection of 2 to 4 degrees F is afforded by the covers, but the biggest benefit is growth enhancement provided by increased daytime solar heating. However, daytime temperatures may be excessive under the cover if ambient temperatures are above 90 degrees F. Under those conditions, partial removal of the cover may be necessary, especially for tomatoes and peppers that have open blossoms.

Advantages of slitted/perforated row covers:

• Outdoor crops may be planted about 10 days earlier than normal.
• Perforated covers provide highest heat retention.
• Slitted covers provide heat retention with more ventilation.
• Earlier maturity and higher yields.
• No manual ventilation necessary.
• Excellent for tomatoes, pepper, cucumbers, melons, and many other crops.
