Cha Ching is engineered to maximize the final phase of a plant's production. Cha Ching is made to be used after the fruit has set. Cha Ching is packed with just the right combination of nutrients to make fruits and flowers drip with flavor and ooze fragrance. Cha Ching is a high phosphorous fertilizer that won't leave behind a salty residue or buildup in your hydroponic or organic systems. Cha Ching contains all the essential elements like calcium, magnesium, boron, manganese, sulfur, molybdenum, iron, copper, and zinc. Cha Ching is designed to work with Fox Farm's other fertilizers.
