This coco substrate has the same qualities as CANNA’s other coco substrates but has a coarser structure that is particularly suitable for the experienced coco user. There is a special line of nutrients for CANNA COGr, called CANNA COGr Vega and CANNA COGr Flores. The COGr board also requires a special buffering agent.
