Once applied to the bed and exposed to sunlight, this mulch permanently shrinks, conforming to the surface of the bed. The tight fit and tough molecular structure reduces wind damage, allowing for better moisture and heat retention. Manufactured to be half as thick and 40% lighter than standard black mulch film, Solar Shrink rolls are more efficient and easier to handle when laying. The lower weight means less plastic to dispose of at the end of the season. Excellent choice for home gardeners and commercial growers. Ideal for organic growers. Dimensions: 48" x 4,000'.
