CalMag for plants
CalMag is short for Calcium & Magnesium fertilizer supplements. Calcium and Magnesium are essential nutrients for healthy growth and development in your plants.
Calcium helps fortify cell walls which in turn helps your plants transport nutrients.
Magnesium plays an important role in photosynthesis (the process by which plants produce energy from sunlight) by stabilizing the chlorophyll molecule.
Powder CalMag
Powdered fertilizers are more concentrated than liquids and are easier to ship and store in large quantities. Powders require dissolving in RO water using mixing equipment before they are ready to use. Best for experienced growers and commercial operations.
