Dutchpro CalMag - Calcium and Magnesium

Dutchpro CalMag is a professional additive designed to prevent and correct calcium and magnesium deficiencies in the plant feeding programme. It is ideal for improving cell-wall structure and stimulating healthy growth.

Dutchpro CalMag is a specialised additive designed to provide optimal calcium and magnesium levels, vital for plant development. It is formulated to prevent deficiencies that often occur with soft water or intense lighting, which increase demand for these minerals. Dutchpro CalMag supports strong cell walls, improves resistance to stress and disease, and helps nutrient uptake for stronger growth and healthier plants. Directions: start from the first week of vegetative growth and add between 0.4 ml and 4 ml per 4 l until flushing. Use CalMag when supplementing CO2 and your CO2 PPM is above 1000 PPM.
