Dutch Pro CalMag
Calcium and magnesium are two of the macro elements that are significant to the growth and development of plants. Calcium (Ca) is a critical structural component of cell walls. Magnesium (Mg) is part of the chlorophyll molecule, which makes up the green pigment of leaves and, most importantly, absorbs energy from sunlight, which creates sugars. Our Calmag is highly concentrated and prevents calcium/magnesium deficiencies. This allows your plants to grow and develop at a maximum rate.
Advanced Growing Styles
When growing with additional CO2, Calcium & Magnesium are needed to keep the plant green and healthy. When you increase your CO2, the plants' needs change, and more Calcium and Magnesium are needed to maintain healthy growth and plant strength. Calmag also fights Magnesium and Calcium deficiencies and works to increase your yield.
