CANNA Coco Coir Bricks Coco Brick 40L 2-Pack — Washed, pH‑Buffered Expands to 80L

CANNA Coco Brick 40L (2-pack) provides two easy-expand compressed coco coir bricks that yield 80 liters of washed, buffered growing medium when hydrated.

These two compressed 20 L bricks per pack are designed to make handling, storage and preparation of coco coir straightforward for hobbyists and commercial growers alike. The product arrives compact and expands with water into a consistent, aerated substrate; it’s intended for use with a dedicated coco nutrient program. Preparation is simple: hydrate gradually, break up any clumps, and transfer the finished medium using the bag’s built-in handles.

How do I prepare the CANNA coco bricks for planting?

Preparing the compressed bricks is a step-by-step process that takes only a few minutes. Hydrate slowly so the coir expands evenly; lukewarm water speeds the process and helps reduce effort when breaking up clumps.

• Open the expansion bag and place the brick on a stable surface.
• Add 0.5–1 L of clean water at a time, pouring into the central hole until fully expanded.
• Loosen any remaining lumps with hands or a garden tool to create a uniform texture.
• Use the bag’s grip handles to lift or transport the prepared coco medium.

What volume will I get and can I mix smaller batches?

Each nominal pack contains two 20 L compressed bricks; the pair in this box expands to about 80 L of usable medium. If you need a smaller quantity, split a compressed brick along the fracture line to hydrate only a portion.

• Contents: 2 nominal 40 L packs (each pack has two 20 L bricks) totaling 80 L expanded.
• For ~10 L batches, divide a 20 L brick along the molded fracture line before adding water.
• Hydrate only the portion you need to avoid waste or long-term storage issues.

Is this coco coir ready to use straight away or does it need buffering and washing?

CANNA supplies washed and buffered coco, which reduces the need for additional pre-washing in most situations. Despite that, it’s meant to be used with a suitable coco-specific nutrient schedule rather than plain potting mixes or soil fertilizers.

• Product arrives washed and pH-buffered for improved nutrient stability.
• Pair with a dedicated coco nutrient program for best results.
• Not a soil replacement with embedded nutrients—add fertilizers as required.

How should I store or reuse leftover expanded coco?

Prepared coco can be reused across multiple cropping cycles if cleaned and reconditioned properly. Store dry, in a cool place, and refresh buffer and nutrients before reuse.

• Dry any used coco thoroughly before long-term storage to prevent odors or mold.
• Store in a sealed container or bag away from direct sunlight and pests.
• Recondition used coco with nutrient flushing, re-buffering, and pH checks prior to replanting.

Who is this for? CANNA Coco Brick 40L (2-pack) is intended for growers who want a reliable, easy-to-handle coco coir medium that scales from small home projects to larger tent or greenhouse setups. It suits gardeners who prefer compressed packaging for storage and those who follow a coco-specific feeding program. Plants, pots and nutrients are sold separately.
