Canna Calmag Agent
CANNA CALMAG AGENT is a specialised calcium and magnesium supplement designed to optimise water quality and correct nutrient deficiencies in soft water or reverse osmosis (RO) systems. It ensures a stable base for your nutrient mix, preventing common issues like calcium lockout, magnesium deficiency, and weak plant structure.
Essential for healthy cell development, chlorophyll production, and nutrient transport, calcium and magnesium are key building blocks for vigorous growth. CANNA CALMAG AGENT not only balances your water profile but also enhances the overall stability of your nutrient solution, improving uptake and reducing the risk of nutrient imbalances.
It’s particularly useful in areas with soft or purified water, where mineral levels are too low to support optimal plant development. Regular use can lead to stronger stems, healthier leaves, and improved resistance to stress throughout the grow cycle.
Why it’s a smart addition:
- Corrects soft water deficiencies and stabilises nutrient uptake
- Improves plant structure, vitality, and nutrient transport
Simply add to your feed water before base nutrients, adjusting the dose depending on your water hardness (typically 0.1–0.4ml per litre). Compatible with all CANNA lines and suitable for soil, coco, and hydroponic systems.
Available in 1L and 5L sizes to suit any scale of growing.
