Cal-Mag Emerald Harvest | Calcium & Magnesium Supplement for Plants

Cal-Mag by Emerald Harvest is a premium calcium and magnesium supplement formulated to boost vigorous growth, strengthen roots, and improve the uptake of essential nutrients in all types of grow systems. Unlike standard Cal-Mag products, this formula includes kelp extract (seaweed)—a natural source of nitrogen, minerals, and bioactive compounds that enhance overall plant performance.
