CANNA Coco Coarse

No. Coco Coarse has been developed to deliver the open structure, drainage and aeration characteristics growers expect from pebble or perlite blended coco mixes without the need for additional inert materials. Carefully selected larger grade coco fibers and a proportion of rice husk create these physical properties while keeping the entire substrate available for root development.

No. Coco Coarse is fully buffered and lightly pre fertilized to provide a stable starting environment and a small nutrient reserve. It is not intended as a long term nutrient source. Begin feeding with a dedicated coco nutrient, such as CANNA Coco A&B or CANNA COGr Vega and Flores, from the first irrigation, at the relevant EC-level

Yes. Although Coco Coarse is fully buffered, this buffering is designed to optimize nutrient availability within the substrate rather than regulate irrigation water pH. Always adjust the nutrient solution to a pH between 5.5 and 6.5 before watering, ideally around pH 6.0.

For most cultivation systems, CANNA Coco A&B is the recommended nutrient. Where irrigation strategies involve higher run off, smaller containers and multiple irrigation cycles per day, CANNA COGr Vega and COGr Flores are the preferred choice.

Yes. Coco Coarse has been developed specifically for cultivation systems that benefit from a more open substrate structure, including gravity fed systems, ebb and flow and drip irrigation. It provides excellent drainage and aeration while maintaining maximum usable root zone volume. In our research trials, Coco Coarse consistently delivered superior performance compared with other coarse coco blends in these applications.

Coco Coarse delivers the familiar drainage, aeration and irrigation characteristics of pebble and perlite blended substrates without occupying valuable root zone space. This allows roots to utilize the full substrate volume while maintaining irrigation strategies that growers are already familiar with.

Yes. Irrigation frequency, nutrient dosing and general cultivation practices remain very similar to pebble or perlite blended substrates. In most cases, little or no adjustment to existing irrigation schedules is required.

It depends on the cultivation system, but Coco Coarse offers several advantages. It provides comparable drainage, aeration and water management while maximizing usable root zone volume, maintaining the naturally high cation exchange capacity of coco and eliminating the need for inert materials. In wetter cultivation systems, it consistently outperformed comparable substrates during our research trials.

Rice husk helps create the naturally open, highly aerated structure that characterizes Coco Coarse. It also provides a slow release source of naturally occurring silica, complementing the larger grade coco fibers that define the substrate's physical properties.

No. Unlike peat based substrates, coco fibers naturally maintain a stable physical structure over time. The larger grade fibers used in Coco Coarse help preserve aeration and drainage throughout the cultivation cycle without the need for added pebbles or perlite.

CANNA Coco Professional Plus is designed for growers who prefer a substrate with a higher water holding capacity. CANNA Coco Coarse is designed for growers who require a more open, highly aerated substrate, particularly in cultivation systems with frequent irrigation, higher run off or naturally wetter root zone conditions.

Yes. Like our other high quality coco substrates, Coco Coarse can be reused when managed correctly. Before reuse, remove as much root material as possible and thoroughly flush the substrate. Proper preparation helps maintain its physical properties and performance for subsequent crops.

Yes. Coco Coarse has been developed for both hand watering and automated irrigation systems. Its open structure, excellent drainage and aeration make it particularly suitable for growers using larger containers or frequent irrigation.

Yes. Coco Coarse is suitable throughout the entire cultivation cycle. Fully buffered and lightly pre fertilized, it provides a stable starting environment for young plants and supports healthy root development throughout cultivation when used with the appropriate CANNA coco nutrient program.

Growers have successfully used pebble or perlite blended coco mixes for many years to improve drainage and aeration in wetter cultivation systems. Coco Coarse was developed to deliver these same physical characteristics while eliminating the need for inert materials that reduce usable root zone volume. The result is a substrate that maintains the familiar irrigation behaviour growers expect while making the entire substrate available for root development.

Developing a new substrate involves far more than changing ingredients. It requires years of research, product development and cultivation trials to achieve the right balance of physical and chemical properties. Coco Coarse is the result of that long term development process and was only introduced once it consistently delivered the performance growers expect from CANNA.
