Dennerle Plants Power Caps provide an ideal mixture of essential macro nutrients (nitrate, phosphate, potassium) and micro nutrients (iron, trace elements) for supplemental fertilization of the substrate. These capsules are designed to be inserted deep at the base of the plant, encouraging root growth, health and vitality. Perfect for strongly rooting species like Echinodorus, Cryptocorynes, and other stem plants, Power Caps can replace or supplement depleted nutrients in the substrate over time.
