Calmag: Prevents & Overcome Deficiencies

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.
