Emerald Harvest - Cal-Mag


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

Grow Lush, Green Plants Emerald Harvest Cal-Mag is more than just a calcium-magnesium supplement. In contrast to competing products, our Cal-Mag contains kelp extract, a natural source of nitrogen and other helpful compounds, making it different from standard products of its kind. Cal-Mag helps minimize the risk of calcium or magnesium deficiencies when you use coco coir and other growing media, provides chelation to help your plants absorb more nutrients and results in greener, stronger, more productive crops.

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
