Why Noweed Premium stands out from other fabrics which appear to be the same, is its construction. An ordinary woven polypropylene pools water and prevents air flow, resulting in poor soil and poor growth. Noweed Premium breathes! Manufactured as a fibralated woven material designed to prevent weed growth and yet allow air to circulate! Soil is not soured and roots are protected from the spread of fungus and bacteria. Specification: 0.91m x 100m, 110gsm. Thread count (weave) is 96 x 44 / 10cm.
