Essential Foundation for Complete Hydroponic Nutrition: This product provides 3.2% calcium, 1.2% magnesium, and chelated iron - the vital secondary nutrients that base fertilizers are missing. Part of a 4-part system made for DWC, NFT, ebb and flow, drip systems, and coco coir growing. Always add first before other nutrients. Crucial for RO Water and Coco Coir: Reverse osmosis and distilled water contain zero minerals - this product restores what's absent.
