Designed to expand into a lightweight, airy substrate when hydrated, it provides an ideal balance of moisture retention, aeration, and drainage for healthy root development.\u003c\/p\u003e \u003cp\u003eProcessed through multiple rinsing stages, this low-EC coco coir is formulated to reduce salt content and maintain a stable pH environment, supporting consistent plant growth. Once expanded, it becomes a fluffy, soil-like medium suitable for use on its own or as an additive in custom potting mixes.
