Description

Emerald Harvest Cal-Mag is designed to nourish crops with extra calcium and magnesium and create the right conditions for abundant flowering and a heavy yield.

Containing top-quality ingredients, this is especially important when growing in some media, such as coco coir, but any garden can benefit.

Growers use calcium-magnesium supplements to strengthen their plants and correct nutritional deficiencies inherent to some popular growing media. Calcium regulates growth and encourages plant development, while magnesium is essential for chlorophyll production, so your garden gets enough energy from light. Magnesium also activates enzymes your valuable plants need to uptake nutrients.

Use Cal-Mag as a supplement to a base nutrient series for guaranteed professional results.

Tips:

• Use as needed, rather than as part of your regular feeding schedule. For example:
  It can feed 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.
  It can help minimize the risk of deficiencies when you use other brands’ base nutrients that may not have as many essential elements. (Emerald Harvest’s 2-part and 3-part professional base nutrient series contain the essential elements plants need to grow).

• Soak coco coir and other soilless growing media with CalMag before planting.

Characteristics:

• Appearance: dark brown to black liquid.
• Aroma: like saltwater, but a bit “funky” like the beach.
• Texture: mildly viscous and a bit oily.
• Spoilage: has a shelf life of 3 years or more if kept under normal conditions
