Product description
Grow Island presents: DutchPro Calmag – Precise calcium and magnesium supply for stable, high-performance plants
Premium supplement for healthy plant structure and maximum vitality
With DutchPro Calmag, Grow Island expands its range with an essential additive specifically developed to reliably correct calcium and magnesium deficiencies. These two minerals are among the most important building blocks of stable plant development and play a key role in cell formation, photosynthesis, and nutrient transport. Especially in modern growing systems such as hydroponics, coco, or when using soft water, calcium and magnesium deficiencies occur frequently – this is exactly where DutchPro Calmag comes in.
This new Grow Island product is aimed at demanding growers who want to supply their plants in a controlled, efficient way and maintain consistently high standards. Thanks to its highly bioavailable formulation, nutrient deficiencies can not only be corrected but also prevented in advance.
Why calcium and magnesium are essential for plants
Calcium – the foundation of cell stability and growth
Calcium is a structural nutrient that plays a decisive role in the stability of cell walls and plant tissues. Without sufficient calcium, plants lose firmness, which negatively affects root development, shoot growth, and resistance. Young, fast-growing plant parts in particular require a constant supply of calcium.
DutchPro Calmag provides calcium in a form that can be absorbed directly by the plant and integrated into the cell structure. The result is stronger stems, more resilient leaves, and significantly improved resistance to stress from heat, cold, or mechanical strain.
Magnesium – the engine of photosynthesis
Magnesium is the central component of chlorophyll and therefore indispensable for photosynthesis and energy production. Magnesium deficiency often appears as leaf discoloration and reduced growth performance. Without sufficient magnesium, the plant cannot efficiently utilize light energy.
Regular use of DutchPro Calmag stabilizes magnesium supply, resulting in deeper leaf color, enhanced photosynthesis, and vigorous growth – the foundation for healthy plants and high yields.
DutchPro Calmag – targeted deficiency prevention in all growing systems
When using reverse osmosis water, soft tap water, or coco substrates, natural sources of calcium and magnesium are often lacking. DutchPro Calmag was developed precisely for these conditions and integrates seamlessly into any existing nutrient strategy.
Grow Island recommends DutchPro Calmag both as a preventive supplement and for the acute correction of deficiency symptoms. Its precise dosing allows flexible adjustment to plant type, growth stage, and substrate.
Application and dosage
DutchPro Calmag can be used during both the growth and flowering phases.
Recommended dosage:
- 0.1 – 1.0 ml per liter of water
- Depending on water quality, substrate, and plant demand
The product is simply added to the nutrient solution or irrigation water and is fully compatible with all common fertilizer systems. Regular use ensures stable nutrient ratios and prevents long-term deficiencies.
