Next to CANNA Coco there is also CANNA COGr, a coco substrate with the same qualities but a coarser structure that is particularly suitable for the experienced coco user.
Nutrients can be given more precisely when using this coco substrate than with any other. COGr boards are pressed and consequently take up very little space,
which is ideal for transportation. The boards are reconstituted prior to use to restore their volume. CANNA COGr Vega and Flores are the nutrients which have been specially developed for use with COGr.
