EMERALD HARVEST CAL MAG 1L

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

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

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 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.

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.
