Description
The Vivosun Coco Coir Brick (1.4 lbs, 3-Pack) is a 100% natural and organic growing medium made from compressed coconut husk fibers. 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.
Processed 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. Its structure promotes strong root oxygenation while retaining enough moisture and nutrients to reduce watering frequency. Compact and easy to store, each brick expands rapidly with water and is suitable for a wide range of gardening applications including seed starting, hydroponics, container gardening, and soil conditioning.
