Coconut fibre is the outer layer of the coconut shell. Widely used as a growing medium because of its fibrous structure similar to peat: coconut fibre can absorb and retain up to eight times its own weight (in this case 4 litres of nutrient solution) of water and store it for long periods. The space between the fibres provides good ventilation. As inanimate organic matter, it is not susceptible to mould. It can be used in most soil cultivation methods, as a sole medium or to amend soil mixtures. Its advantages can also be exploited as a separate aquifer.
Main features
washed but not buffered* (Non-buffered - only washed coconut fiber must be treated with calcium before use: buffering!)*
weight: 4.5 kg
conductivity < 0.4 ms/cm2
compression ratio: 1:5
fibre length: < 4 mm
moisture content: < 20%
pH: 5,5 - 6,5
* Buffering solutions are specifically designed to replenish calcium and magnesium. After buffering, the coconut bricks are considered equivalent to our buffered coconut products, so any coconut food can be used with them! The CANNA COGr Buffer Agent nutrient solution has been specially developed for this purpose: to prepare and pre-treat the growing medium. It contains pH stabilizers, silicon, humic and fulvic acids to infuse and replenish the medium with nutrients. Therefore, the coconut brine must be treated with such a solution prior to use.
