CANNA Calmag Agent is a specialised water conditioner and a Cal-Mag supplement developed specifically for the soft water conditions found across NZ and Australia. It's designed to create the ideal base water for coco grows using reverse osmosis (RO) or naturally soft water.
Soft water makes it harder for plants to access the nutrients they need. CANNA Calmag Agent balances calcium and magnesium, raises the EC to an ideal starting point, and creates a stable foundation for healthier growth, stronger plants and better-quality harvests.
