Product detailed description
CANNA Coco Coarse is a premium coarse coco growing medium of a new generation, designed for growers who require excellent aeration, fast drainage and optimum conditions in the root zone. It offers an open structure similar to coco mixes with expanded clay or perlite, without the need to add these inert materials.
The combination of carefully selected coarse coco fibres, coco fibre and rice husks creates a naturally open growing medium with excellent drainage of excess water. The entire volume of the medium remains available for root system development.
No expanded clay. No perlite. No problem.
Key benefits of CANNA Coco Coarse
- open structure with fast drainage
- high aeration in the root zone
- optimised air-to-water ratio
- maximum use of the container volume for root growth
- lower risk of overwatering plants
- ideal for frequent and automated irrigation
- suitable for AutoPot, ebb & flow and drip irrigation
- pre-buffered and lightly pre-fertilised
- ready to use straight from the bag
- free from perlite and expanded clay
More usable space for roots
Perlite or expanded clay is commonly added to coco growing media to increase drainage and aeration. However, these inert materials also take up part of the container volume that the root system cannot fully use.
CANNA Coco Coarse achieves the desired open structure through the composition of the medium itself. This allows the roots to use practically the entire volume of the growing container. Compared with a growing medium containing 40 % expanded clay, Coco Coarse can offer up to 40 % more usable root space. In a 10-litre pot, this means up to 4 litres of extra space for root development.
Excellent drainage and aeration
The specific structure of the coarser coco fibres creates an optimum balance between air and water in the root zone. The medium drains excess water quickly while maintaining sufficient moisture availability for plants.
Lower overall water retention, together with high aeration, helps maintain a healthy root environment and reduces the risk of overwatering. CANNA Coco Coarse is therefore particularly suitable for systems with more frequent irrigation or higher humidity in the root zone.
Ideal for automated irrigation
CANNA Coco Coarse was also developed for modern irrigation systems. Its open structure and fast drainage make it suitable for frequent irrigation cycles and various methods of automated irrigation.
The growing medium is particularly suitable for:
- AutoPot and other gravity-fed irrigation systems
- drip irrigation
- ebb & flow flood systems
- high-frequency irrigation
- hydroponic growing
- hand watering
- growing in larger containers
It is particularly well suited to high-frequency irrigation, where fast drainage of excess water and sufficient oxygen in the root zone are important.
Pre-buffered and lightly pre-fertilised
CANNA Coco Coarse is pre-buffered during manufacture. The initial EC of the growing medium is approximately 1.4 +/-0.2 at an extraction ratio of 1:1.5.
Buffering helps stabilise the cation exchange capacity of the coco medium, particularly in relation to the availability of calcium and potassium.
The medium is also lightly pre-fertilised with a starter fertiliser NPK 12-14-24, which provides young plants with a basic supply of nutrients during the initial rooting phase.
However, this pre-fertilisation is not intended as complete nutrition for the entire growing cycle. Using a suitable coco fertiliser is recommended from the first watering.
Rice husks for a more open structure
CANNA Coco Coarse contains sanitised rice husks, which help create an open structure in the growing medium and improve drainage and oxygen access to the roots.
Rice husks are also a natural source of silicon, which is released gradually. However, this is only a long-term supplementary source and does not replace separate silicon supplementation if higher doses are required.
Composition of CANNA Coco Coarse
- buffered and washed coco fibre
- buffered and washed coarse coco fibres
- sanitised rice husks
- starter fertiliser NPK 12-14-24
How to use CANNA Coco Coarse?
- If the medium has settled during transport, gently loosen it before use.
- Fill the growing container with CANNA Coco Coarse.
- Transplant the plant directly into the medium.
- Fertilise from the first watering with a suitable coco fertiliser.
- Keep the pH of the nutrient solution between 5.5 and 6.2, generally around 6.0.
- Adjust the irrigation volume and frequency to the size of the plant, container volume, environmental conditions and growth phase.
Recommended fertilising
For most growing systems, the manufacturer recommends using CANNA COCO A&B.
For high-frequency irrigation with greater runoff, typically 10 % or more, such as in smaller containers irrigated several times a day, CANNA COGr Vega & Flores is more suitable.
- minimum runoff: CANNA COCO A&B
- higher runoff of 10 % or more: CANNA COGr Vega & Flores
CANNA Coco Coarse is also compatible with RHIZOTONIC, CANNAZYM, CANNABOOST, CANNA Silica and CANNA PK 13/14.

CANNA Coco Coarse vs. CANNA COCO Professional Plus
CANNA Coco Coarse is not a replacement for CANNA COCO Professional Plus. The two growing media are intended for different growing methods.
CANNA COCO Professional Plus is suitable for growers looking for a universal coco growing medium with higher water capacity. CANNA Coco Coarse, on the other hand, has a more open and more highly aerated structure with lower water retention.
It is therefore particularly suitable for more frequent irrigation, automated systems and conditions in which the root zone tends to be naturally more humid.
Frequently asked questions
Do I need to add perlite or expanded clay to CANNA Coco Coarse?
No. CANNA Coco Coarse was developed to provide the required drainage and aeration through its own structure. There is no need to add perlite or expanded clay.
Is CANNA Coco Coarse suitable for an AutoPot system?
Yes. Its open structure, good drainage and high aeration make Coco Coarse a very suitable medium for AutoPot and other automated or gravity-fed irrigation systems.
Does the medium need to be flushed before use?
No. CANNA Coco Coarse contains washed and buffered coco fibres and is ready to use. If the medium has settled during transport, it is recommended that you simply loosen it before filling the container.
Is watering the plants with water alone sufficient?
No. The medium is only lightly pre-fertilised, and its initial supply of nutrients is not intended as complete nutrition for the entire growing cycle. Use a specialised coco fertiliser from the first watering.
What pH should the nutrient solution be?
The recommended pH of the nutrient solution is 5.5 to 6.2. The manufacturer generally recommends aiming for approximately 6.0.
Can CANNA Coco Coarse be used throughout the entire growing cycle?
Yes. CANNA Coco Coarse can be used from transplanting young plants through to the end of the growing cycle when used with an appropriate fertilising programme.
Can the growing medium be reused?
Yes. Before reusing it, remove as much of the old root material as possible and flush the medium thoroughly. When preparing for the next growing cycle, the manufacturer also recommends using CANNAZYM.
Storage
- store in a cool, dry place
- keep the bag sealed until use
- protect from direct sunlight and excessive heat
- do not expose to rain or standing water for extended periods
- handle carefully to preserve the structure of the growing medium
CANNA Coco Coarse is a modern alternative to coco mixes with perlite or expanded clay. It provides an open structure, high drainage and plenty of oxygen for the roots, while keeping the entire volume of the growing container available for root system development.
