Plagron Hydro A & Hydro B

Two component nutrient for the growth and flowering phase

Hydro A&B is a highly concentrated mineral basic plant nutrition for use during the plant’s growth and flowering phase. It contains all trace elements in a quickly absorbable (chelated) 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.

Dosage and use

Shake well before use. Add a maximum of 2.5 ml Hydro A per 1 litre of water (1:400). With every application of Hydro A use the same quantity of Hydro B. Use this solution each time the plants are irrigated.
