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.\u003c\/p\u003e\u003cp\u003eEdge 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.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2.5 lb\u003c\/li\u003e\n\u003cli\u003e6.6 lb\u003c\/li\u003e\n\u003cli\u003e25 lb - makes 12.5 gal of stock concentrate at 2 lb per gal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGuaranteed analysis 14-0-0 with 21% calcium\u003c\/li\u003e\n\u003cli\u003eNitrogen: 14% total (3% ammoniacal, 11% nitrate) to drive vegetative growth and cell expansion without excess ammonium\u003c\/li\u003e\n\u003cli\u003eAlso supplies 0.01% magnesium, 0.04% sulfur, 0.006% chelated iron and 0.01% manganese\u003c\/li\u003e\n\u003cli\u003eDerived from calcium ammonium nitrate, iron EDTA and manganese EDTA\u003c\/li\u003e\n\u003cli\u003eHighly soluble with zero residue; compatible with other nutrients in fertigation systems\u003c\/li\u003e\n\u003cli\u003eDirect dilution reference: 1\/2 tsp (3 g) per gal = EC 1.0; 1 tsp (6 g) per gal = EC 2.0\u003c\/li\u003e\n\u003cli\u003eSDS hazard: harmful if swallowed and causes serious eye damage - wear gloves and eye and face protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCommercial fertigation and dosing systems running stock concentrates\u003c\/li\u003e\n\u003cli\u003eCorrecting calcium deficiencies in high-yield indoor cultivation and greenhouse facilities\u003c\/li\u003e\n\u003cli\u003eCalcium and nitrate nitrogen supplementation alongside Grow and Bloom dry bases\u003c\/li\u003e\n\u003cli\u003eDrip irrigation systems that need clean, residue-free calcium sources\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Global Garden Company","offers":[{"title":"2.5 lb","offer_id":53075631145271,"sku":"BL226093","price":27.0,"currency_code":"USD","in_stock":true},{"title":"6.6 lb","offer_id":53075631178039,"sku":"BL226094","price":69.0,"currency_code":"USD","in_stock":true},{"title":"25 lb","offer_id":53075631210807,"sku":"BL226095","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/eh-edge-dry_1.jpg?v=1790823951","url":"https:\/\/www.blacklabelsupply.io\/products\/emerald-harvest-edge-calcium-supplement-dry-formulation","provider":"BLACK LABEL","version":"1.0","type":"link"}
