Emerald Harvest Cal-Mag is a premium calcium-magnesium supplement formulated to keep plants lush, green, and productive in any growing medium. Essential for preventing nutrient deficiencies common in coco coir and other substrates, Cal-Mag provides the building blocks for strong cell walls and healthy chlorophyll production. Calcium supports structural integrity and growth, while magnesium powers photosynthesis and activates key enzymes for nutrient uptake.
