Soil Moist Seed Coat is a crosslinked polyacrylate and graphite compound. It is designed to increase the germination of grass and other types of seeds. The polymer compound retains excess moisture from water and humid air. The moisture on the seed softens its tissue to promote faster germination. The graphite compound retains heat on the surface of the seed to promote germination. The graphite helps lubricate the seed and equipment to help spread the seed. 8 oz. ounce of Seed Coat material will treat 50 lbs. of grass seed.
