Emerald Harvest - Edge Calcium Supplement Dry Formulation

Brand: Emerald Harvest

Emerald Harvest Edge Calcium Supplement Dry Formulation

Emerald Harvest Edge is a 14-0-0 dry calcium supplement with 21% calcium, made for growers who expect uncompromising quality and predictable results. Unlike basic calcium nitrate products, Edge delivers system-compatible, fast-acting calcium and nitrate nitrogen with complementary chelated iron and manganese, manufactured from premium raw materials under strict quality controls. It corrects calcium deficiencies that limit growth and builds thicker cell walls and stronger tissue.

Edge is highly soluble with zero residue to prevent clogging and is compatible with other nutrients across fertigation systems. To make a 2 lb per gallon stock concentrate, fill the reservoir with 6 gal of water, slowly add a 25 lb bag while mixing, top up to 12.5 gal and mix until all granules are dissolved; for direct dilution use 1/2 to 1 tsp per gallon of water (2.5 to 5 g per 4 L). Edge is part of the Emerald Harvest dry line alongside Grow and Bloom.
