Overview

Prevent & treat nutrient deficiencies with Emerald Harvest Cal-Mag.

It's a calcium (3%) & magnesium (0.5%) additive in coco, which holds onto calcium, it's a neal crop-saver. Whatever your media, it provides chelation to help nutrient absorption.

Not only does it prevent deficiencies - it improves growth. Calcium regulates growth, and magnesium is key for chlorophyll production (photosynthesis!).

Calcium (3%) & magensium (0.5%) additive
Prevent & treat nutrient deficiencies
Regulate growth & chlorophyll production
Coco essential!
NPK: 2-0-0

How It Works

Caclium and magnesium are both macronutrients. Plants need them to survive.

Calcium

Calcium is used to thicken stems and your structure by binding cell walls. It's crucial for growth. A deficiency of it makes it tougher for plants to cope with temperature and environmental stresses.

Since calcium is involved in processes that affect the uptake of other nutrients, a shortage of calcium can increase the likelihood of other nutrient deficiencies.

Magnesium

Magnesium is in chlorophyll - the green substance that absorbs light for photosynthesis.

If you've got high intensity lights, or plants are growing rapidly, you don't want to risk a magnesium shortage.

In Coco

Coco is known for its calcium draw. It has a tendency to hold onto calcium, making it unavailable to your plants. For this reason, you should always use a Cal-Mag in coco.
