Lasting for up to 10 years and developed as the ideal protection for vegetable crops following many years of research. 25 years of usage in the U.K. has proved its reliability and durability. This very finely woven netting keeps out pests such as cabbage and carrot root flies, pea moth, cutworm, leaf miners, caterpillars, birds and rabbits. It also protects from wind and hail allowing air, light and moisture through to provide the perfect growing environment for a wide range of crops. Gives a small amount of protection from frost. Just place over the crop and secure with staples or stones.
