Product description

CANNA COGr Buffer Agent is a special liquid that is used to soak and buffer COGr boards. CANNA developed this agent especially for the preparation of this growing medium.
User Instructions: add COGr Buffer Agent to the nutrient reservoir with the dilution ratio 1:500 (200 ml per 100 litre of water).
Recommended pH-value: 5.5 - 6.2.
Add ± 12,5 litres of buffer-solution to each slab.
Let the swollen COGr soak for at least 24 hours before draining it!
Store closed in a dark and frost-proof place (UV light breaks down iron chelates in the nutrient).
Keep out of reach of children.
