CANNA COGr Buffer Agent 1 L - Calcium and Magnesium Buffering Agent

CANNA COGr Buffer Agent is a special liquid used for soaking and buffering* COGr slabs. CANNA developed this solution specifically to prepare this growing medium.

User instructions:

• Shake the bottle well before use
• Fill the reservoir with water
• Add COGr Buffer Agent to the nutrient tank at a dilution ratio of 1:500 (200ml per 100 litres of water)
• The EC of COGr Buffer Agent dissolved in (tap) water ranges from 1.5–1.8 mS/cm² (= EC of the solution + EC of the water)
• Recommended pH: 5.5 - 6.2
• Add ± 12.5 litres of buffer solution to each slab
• Leave to soak for at least 24 hours

Storage, health and safety, and other guidance:

• Over-fertilisation has a negative effect on the substrate, the plant and nature as a whole!
• Store in a dark place (UV light breaks down iron chelates in the nutrient medium); protect from freezing!
• Keep out of reach of children!
