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.

Liquid CalMag

Pre-blended liquid nutrients are much more convenient and easy to use than powders. Simply measure the volume you need and provided it to your plants during regular watering. Best for home growers and small operations.
