Keep your plants productive and green in any growing medium with this top-quality calcium-magnesium supplement. 

Cal-Mag is especially important for preempting deficiencies when growing in certain media, such as coco coir, but any garden can benefit. 

  • Lush, vibrant, green growth and plant development
  • Optimal chlorophyll production to support photosynthesis
  • Less risk of calcium or magnesium deficiencies due to coco coir

Cal-Mag nourishes crops with supplemental calcium and magnesium, fostering the right conditions for abundant flowering and a heavy yield.

  • Calcium, which helps hold cell walls and membranes together
  • Magnesium, the central atom of the chlorophyll molecule
  • Kelp, a rich, natural source of proteins and biocatalysts
  • Helps prevent rot 

Coco and more

Suitable for plants grown in coco coir or other growing media.
