Hydra-Loc Hydrogel is a granular, non-toxic super absorbent polymer designed to enhance soil moisture retention. Capable of absorbing up to 400 times its weight in water, Hydra-Loc gradually releases up to 95% of the stored moisture—along with essential soil amendments—as the soil dries. This makes it an invaluable solution for hydroseed contractors, landscape professionals, and growers seeking improved water efficiency and plant health.
