This medium weight floating row cover protects plants from wind and insects, and offers additional frost/ freeze protection, without sacrificing light transmission, which is about 75% and provides up to 5-6 degrees of frost protection. The fibers of this type of non-woven row cover are bonded at tiny points, producing a strong, yet reasonably priced crop protection material. These non-woven, porous row covers are ideal for crop protection against insect infestations, wind, emergency frosts/freezes, and overwintering. Row covers help encourage extra earliness for the spring season and allow extension of the growing season into the fall, when prices are likely to be higher. They work by establishing a precise microclimate under the cover. Air, water and light easily penetrate this material. It can be used without support hoops, and the edges should be held in place with soil. Weight: 1 oz./square yd.; Size: 6' x 250'
