Calmag products are a type of hydroponic supplement that provides plants with calcium and magnesium, two essential nutrients that are often deficient in hydroponic systems. Calcium and magnesium play important roles in the growth and development of plants, helping to support cell structure, photosynthesis, and nutrient absorption.

Calmag supplements are particularly important in hydroponic systems, where nutrient levels can fluctuate rapidly, and the pH of the nutrient solution can be difficult to control. In these systems, calcium and magnesium deficiencies can lead to stunted growth, leaf discolouration, and other symptoms of nutrient deficiency.

Other hydroponic supplements may contain amino acids, vitamins, and other nutrients that can help to improve plant growth and health, as well as plant hormones and growth regulators that can help to promote specific growth patterns or flowering cycles.

Plants need all three major plant nutrients - nitrogen, potassium and phosphorus - in order to grow at their best. Using high-quality plant nutrients will help you achieve unrivalled harvests..
