Plagron Hydro A&B

Hydro A&B is a highly concentrated, mineral base fertilizer that is used in the growth and flowering phase of the plant. It contains all trace elements in a rapidly absorbing (chelated) form. Hydro A is rich in calcium, which helps the plant with heat stress, for example. Hydro B, on the other hand, contains magnesium, which stimulates the production of leaf green and is therefore an important building block for plant growth. Hydro A&B therefore complement each other perfectly and together form a complete nutrient combination. Hydro A&B can be used on all types of inert substrates
