Grow Lush, Green Plants
Keep your plants productive and green in any growing medium with Cal-Mag, a calcium and magnesium supplement from Emerald Harvest.
Emerald Harvest Cal-Mag is more than just a calcium-magnesium supplement. In contrast to competing products, EH Cal-Mag contains kelp extract, a natural source of nitrogen and other helpful compounds, making it different from standard products of its kind. 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. 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.
Benefits
You safeguard your crop by avoiding calcium or magnesium deficiencies.
Such deficiencies are all too common and can happen in any garden. However, certain growing media put your plants at a higher risk of deficiencies. In particular, coco coir can lock out some of the calcium and magnesium you feed your plants. Cal-Mag minimizes the risk of calcium and magnesium deficiencies from happening under any growing conditions.
You get a better return on your investment in nutrients.
Cal-Mag increases nutrient uptake. More of the nutrients you feed your crops actually get used as plant food, rather than binding to the growing medium or running to waste:
- Calcium helps lengthen the roots. Longer roots take up more nutrients.
- Magnesium activates enzymes that help plants absorb nutrients.
Cal-Mag promotes crop development:
- Calcium supports vibrant growth.
- Calcium encourages cell division.
- Calcium is essential for strong cell walls.
- Magnesium activates many enzymes required for growth.
- Magnesium assists in the manufacture of proteins, the building blocks of life.
Cal-Mag supports vegetative growth:
- Cal-Mag provides plants with abundant energy for growth and flowering through photosynthesis.
- Magnesium is essential for chlorophyll production; indeed, it is a chlorophyll component.
- Chlorophyll is essential for photosynthesis, the process by which plants convert light into energy by metabolizing carbohydrates.
- Energy drives both vegetative growth and flowering.
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
- Coco and more: Suitable for plants grown in coco coir or other growing media.
- Stop deficiency: Say goodbye to calcium or magnesium deficiency in your garden.
- Greener gardens: Promotes chlorophyll production for more efficient photosynthesis.
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
Product Characteristics
- Appearance: dark brown to black liquid.
- Aroma: like salt water, but a bit “funky” like the beach.
- Texture: mildly viscous and a bit oily.
- Shelf Life: 3 years or more if kept under normal conditions.
Tips & Tricks
Use as needed, rather than as part of your regular feeding schedule. For example:
- Feed Cal-Mag to hungry plants undergoing a rapid vegetative growth spurt, in transition or at peak flowering. During such times, plants greatly benefit from extra calcium and magnesium.
- Apply it to help minimize the risk of deficiencies when you use other brands’ base nutrients that may not have as many essential nutrients. (Emerald Harvest’s 2-part and 3-part professional base nutrient series contain all the essential nutrients plants need to grow.)
- Soak coco coir and other soilless growing media with Cal-Mag before planting.
- Use in place of any calcium magnesium product.
Cal-Mag contains sea kelp extract. It’s an extra ingredient (that Emerald Harvest competitors don’t include) which assists chelation and adds micronutrients. It delivers auxins, cytokinins and other phytohormones to plants, as well as every micronutrient and numerous beneficial compounds.
