Silway water retainer absorbs and retains large quantities of water and nutrients when incorporated into a soil or a substrate.

Unlike most products that become hydrated, Silway water retainer has the property of easily releasing the absorbed water and nutrients, thereby allowing the plant to have water and nutrients available at will as a function of the absorption-release cycles.
