Description
CANNA – CalMag Agent
CANNA CalMag Agent is a high-quality calcium and magnesium supplement developed to optimise soft or low-quality water for hydroponic and soil-based growing systems. Designed by CANNA’s expert team of Dutch horticultural scientists, this powerful additive stabilises EC levels and enhances nutrient absorption, preventing common deficiencies that can stunt growth or reduce yields.
By improving water quality and nutrient balance, CalMag Agent ensures plants develop stronger cell walls, vibrant green foliage, and more robust flowering sites. It’s an essential supplement for growers using reverse osmosis (RO) water, rainwater, or soft tap water.
Key Benefits:
Corrects calcium and magnesium deficiencies in soft or RO water.
Improves nutrient uptake and overall plant health.
- Ideal 3:1 Calcium Magnesium ratio.
Enhances strength, colour, and growth rate.
Prevents blossom-end rot, leaf yellowing, and weak stems.
Stabilises EC and pH for consistent feeding results.
Instructions for Use:
Shake well before use.
Add 0.1–0.5 ml per litre of water to adjust calcium and magnesium levels until you reach an EC of 0.4.
Use during both vegetative and flowering stages as needed.
Monitor EC and pH after adding to ensure optimal nutrient balance.
- Can be used alongside any other nutrient range.
