Hydro A & Hydro B
Base nutrient

Two component nutrient for the grow and flowering phase

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 (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 10 ml Hydro A per gallon 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.

Hydro A
NPK (3-0-1)
CaO 5.9%
MgO 0.4%

Hydro B
NPK (1-3-6)
MgO 1.4%

Should I regulate the pH and EC value if I grow with Hydro A&B?
Yes, you should regulate the pH value and EC values when growing with Hydro A&B. Hydro A&B already adjust these values in your nutrient solution. However, tap water doesn’t have the same pH and EC value everywhere. We recommend a pH value between 5.5 and 6.5. The correct EC value differs for each plant species and its growth or bloom phase. Use our HYDRO Grow Schedule to find out which EC value best fits your plant.

How long can I store Hydro A&B after it has been mixed with water?
Hydro A&B can be stored for four days after they have been mixed with water. Do monitor the pH value, as this will probably start to slowly increase. Make sure that no organic products have been mixed into the solution, as they can start to spoil after just 48 hours. Also ensure the solution is kept moving (circulation pump) and that the tank is clean before you mix the solution.
