Supercharge your cultivation setup with CANNA Coco Coarse, the next-generation, peat-free growing medium engineered specifically for high-performance, fast-growing crops. This innovative substrate breaks away from traditional perlite and clay pebble blends by pioneering a sustainable coco and rice husk matrix. The result is a radically structure-stable, ultra-porous root environment that provides unrivaled air-to-water ratios, ensuring your plants reach their absolute peak genetic potential.

Pre-buffered to strict commercial standards and lightly pre-fertilised to ease young plants into their lifecycle, this premium coarse coir fully synchronises with the complete range of specialized CANNA coco nutrients. It is the ultimate eco-friendly choice for growers seeking explosive root branching, ultra-fast drainage, and foolproof irrigation control.

Advanced Coarse Aeration: Utilises a structural blend of premium coconut fibre, coarse coir chunks, and rice husks to maximise oxygen availability in the root zone.
The Sustainable Alternative: Fully replaces traditional mining-heavy perlite and heavy clay pebbles with a renewable, high-performance organic matrix.
Uniform Hydration: Prevents dry spots and uneven moisture channels by ensuring perfectly even, predictable water distribution throughout the entire container.
Clean and Buffered: Rinsed and buffered to eliminate excess sodium and potassium, protecting delicate root tips from salt burn and nutrient lockout right out of the bag.
Ready-to-Use Foundation: Lightly pre-fertilised to give establishing root networks immediate, gentle support without shocking fragile young plants.

Step-by-Step Directions for Optimal Use:

Pot Preparation: Fill your chosen containers completely with the substrate, ensuring it is lightly settled but not overly compacted to maintain maximum aeration pockets.
Planting: Gently set your healthy seedlings or rooted cuttings directly into the coarse medium.
The Wet-Dry Foundation: Fully saturate the substrate with water or a mild nutrient solution. Allow the medium to dry down significantly before watering again. Initiating these wet-dry cycles forces the root system to actively search for moisture, rapidly building a massive, healthy root architecture. For larger pot sizes, repeat this cycle multiple times.
Gravity System Management: If you are using bottom-fed gravity systems, ensure your plants have completed their wet-dry cycles and established an expansive root network before turning on the main reservoir line.
