Besides the regular CANNA COCO products there is also CANNA COGr. This is a line of nutrients and a special coco substrate, called the CANNA COGr board. 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, called CANNA COGr Buffer Agent. CANNA COGr Vega is the nutrient that is specially intended to be used when growing in CANNA COGr Boards during the growing stage of the plant. This ensures healthy and strong plants that produce long, vigorous growth shoots. COGr Vega is a complete professional nutrient for plants containing all the essential elements for optimal growing. COGr in combination with COGr growing medium is the nutrient for the experienced and demanding grower.
