Coco Coir has a great buffer capacity. On the one hand, this is an advantage because it makes growing with CANNA Coco very user-friendly. However, this also makes it difficult to provide the slab or bag, from the beginning, with the right types and amounts of nutrients.  After years of research by way of soil, run-off and leaf analysis, CANNA was able to develop a fertiliser which is specially adapted to the properties of the Coco substrate. As CANNA Coco contains natural chelates, humic acids and fulvic acids, so the plant can optimally absorb all nutrients.
