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 amount of nutrients. After years of research by way of soil and 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 chelate along with humic and fulvic acids the plant can optimally absorb all nutrients.
