House & Garden™ Cocos® A & B is a two-part base nutrient designed for drain-to-waste hydroponic systems using coco coir, providing a precise ratio of essential nutrients tailored to the unique properties of coco media. Formulated for use in pure coco or blends with at least 30% coco, it delivers the right balance of soluble macronutrients and magnesium to promote vigorous growth, improve plant strength and resilience, and enhance nutrient uptake efficiency.
To use, fill the reservoir with fresh water, then add equal amounts of Part A and Part B at 0.5 to 3 mL per litre (0.4 to 2.2 tsp per gal), mixing thoroughly between each addition. Designed to perform best within a pH range of 5.8 to 6.3, this formulation supports plant development from cuttings through late bloom. Cocos A & B contains no dyes, synthetic PGRs, or detectable heavy metals.
