COGr Boards

CANNA COGr Boards are compressed coco slabs specially formulated for the COGr growing system, offering a coarser fiber structure that retains moisture longer while still allowing for exceptional aeration. Once they’re expanded and soaked with the COGr Buffer Agent, they deliver a high-performance medium that responds beautifully to precise feeding schedules. Each board helps with vigorous root development, nutrient uptake, and massive growth — making them a go-to for experienced cultivators running large-scale or intensive grows. Lightweight, clean, and easy to store until you want to activate them, CANNA COGr Boards are the secret weapon for growers who want maximum control over their grow for the biggest yields possible. If you're already loving the slab life, check out CANNA Coco Slabs for a more conventional, ready-to-use option. For new growers or die-hard soil lovers, simple and nutrient-rich CANNA Terra Professional might be more your substrate style.
