Emerald Harvest Cal-Mag Calcium and Magnesium Supplement

Cal-Mag helps regulate plant growth and productivity and ensures essential chlorophyll levels, especially when growing in coco coir and other inert media. Derived from calcium nitrate, magnesium, sulfate, calcium acetate, magnesium acetate, and kelp extract. Growers use calcium-magnesium supplements to strengthen their plants and correct nutritional deficiencies inherent to some popular growing media. Calcium regulates growth and encourages plant development, while magnesium is essential for chlorophyll production. Magnesium also activates enzymes your plants need to uptake nutrients. Use Cal-Mag as a supplement to your favorite base nutrient series for guaranteed professional results.
