Harris Coco Coir Pith – 4 Bricks Expand to 9 Gallons of Coconut Coir Fiber for Planting

Harris Coco Coir Pith offers a sustainable growing medium sourced from coconut fiber. When you hydrate the four compact bricks, they expand into nearly 9 gallons of soft, airy coco coir, ready to blend with soils or power hydroponic systems. The fluffy, moisture-friendly texture helps distribute nutrients more evenly, supporting healthy root development without compacting soils.

Designed to balance moisture and aeration, coco coir can absorb up to ten times its weight in water, making root hydration more consistent across the root zone. Its airy, sponge-like structure creates natural air pockets for better drainage and root health in pots, containers, and outdoor beds alike. This versatility makes it a practical choice for gardeners who value flexibility in a growing medium.

Versatility for every grower

Indoor or outdoor use means it adapts to a wide range of setups — from seed starting in pots to larger garden beds. The product is suitable for both hydroponic systems and organic blends, appealing to growers who prefer sustainable, renewable inputs and simple handling.

• Healthy planting additive: distributes moisture and nutrients when mixed with soil or potting mixes
• Moisture management: absorbs up to 10x its weight in water for steady hydration
• Aeration boost: fluffy texture creates air pockets to loosen soil structure
• Indoor/outdoor compatibility: ideal for pots, beds, and hydroponic setups
• Versatile growing: supports both organic and hydroponic approaches

How to use

• Soak bricks in warm water until fully expanded, then fluff with your hands
• Mix with potting soil or seed-starting mixes at recommended ratios
• Rehydrate as needed and reuse for multiple cycles

Storage and care: store in a dry place until ready to use; once hydrated, keep the medium evenly moist but not soggy for best results. Outcomes depend on plant type, feeding, and environment.
