CANNA COGR Board 1m

The CANNA COGR Board can absorb large amounts of nutrients, moisture and air all at the same time making them available to the plant when required. This promotes faster root development and higher yields. COGr boards are ideal for transportation as they are delivered in dried and pressed form and weigh less than 2 kilograms.
Please Note: These COGR boards require CANNA’s range of COGR buffers and nutrients.
