Cheardia 12-Pack Coconut Coir Brick – High-Expansion, Low EC & Balanced pH Substrate

Overview

Cheardia presents a 12-pack of coconut coir bricks that expand into a lightweight, breathable planting substrate. Each brick measures 7.8" x 4" x 1.5" and weighs between 300 g and 400 g, depending on moisture content. The material is naturally derived, with low EC and a balanced pH, offering a versatile base for a wide range of garden and container plants.

Key benefits

• 12 compact bricks provide a convenient, space-saving solution that expands into a porous growing medium.
• Natural coconut fiber delivers a lightweight substrate with low EC and balanced pH for gentle plant care.
• The expanded, honeycomb-like structure promotes air circulation and drainage, helping to reduce soil compaction and support root health.
• Simple rehydration: soak in water, wait about 15 minutes, then drain; the expanded material blends well with nutrient-rich soil.
• Versatile use for pots, beds, vegetables, flowers, herbs, and even raised garden systems.

How to use

• Place each brick in a container of water and allow full expansion, typically around 15 minutes.
• Drain any excess moisture, then break apart the expanded material as needed.
• Mix with potting soil that contains nutrients, or use as a base with your preferred feeding plan.
• Water regularly and monitor EC and pH to maintain a balanced growing environment.

Common horticultural uses

• Ideal for potted plants, succulents, vegetables, flowers, and raised beds.
• Enhances soil structure by adding aeration and drainage without adding heavy weight.

Storage and care

Keep bricks in a cool, dry place. Note that final weight varies with moisture, so you may see small differences between batches.
