Hydro A & B is a highly concentrated mineral base plant nutrition for use during the plant’s grow and flowering phase. It contains all trace elements in a quickly absorbable (chela ted) form. Hydro A is rich in calcium which helps the plant against heat stress. Hydro B contains magnesium which enhances the production of chlorophyll, making it an indispensable building material enabling the plant to grow. Hydro A & B complement each other resulting in a complete combination of nutrients. Hydro A & B can be used on all types of inert substrates. Show more
