CANNA COGr Buffer Agent is a special liquid that is used to soak. CANNA developed this agent especially for the preparation of this growing medium.
At the heart of the COGr line lies the COGr board. This board consists of a sophisticated mix of coconut grit, coconut fibre, and coconut granulates.
 
Advantages of the CANNA COGr board:
Thanks to the coarse coconut structure, the COGR board has the unique property of being able to absorb large amounts of nutrients, moisture and air simultaneously, which are made immediately available to the plant.
This makes the medium superior to all other growing media, promoting faster root development and higher yields.
COGr boards are ideal for transportation. They are delivered in dried and pressed form. In this form, they only weigh less than 2 kilograms.
