WHY USE CAL-MAG 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
WHAT MAKES IT WORK?

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
