Emerald Harvest Cal-Mag keeps your plants productive and green in any growing medium with our top-quality calcium-magnesium supplement.

Keep your plants productive and green with Cal-Mag, a calcium and magnesium supplement from Emerald Harvest. Containing top-quality ingredients, Cal-Mag is designed to nourish crops with extra calcium and magnesium and create the right conditions for abundant flowering and a heavy yield by utilizing its 2-0-0 NPK. This is especially important when growing in some media, such as coco coir, but any garden can benefit. Use Cal-Mag as a supplement to a base nutrient series for guaranteed professional results.


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.

What Makes it Work?
