Quick Answer CANNA Coco A & B is a complete two-part mineral base nutrient for growers cultivating plants in coco coir. The same formula is used through vegetative growth and flowering. Add equal amounts of Part A and Part B to water, mixing Part A thoroughly before adding Part B. Product Description CANNA Coco A & B is formulated for the nutrient-holding characteristics of coco substrate. The two-part format keeps concentrated mineral components separate until they are diluted, helping avoid insoluble combinations that plants cannot absorb. The formula contains mineral nutrients, natural chelates, humic acids and fulvic acids. CANNA Coco A & B dissolves directly and is suitable for coco watering systems including run-to-waste, flood, and ebb-and-flow setups. Choose a 1L, 5L or 20L matched A-and-B set to suit the size of your reservoir and growing program.
