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, so your garden gets enough energy from light. Magnesium also activates enzymes your valuable plants need to uptake nutrients.
Use Cal-Mag as a supplement to a base nutrient series for guaranteed professional results.
