Comprehensive information

DutchGrow Hydro A&B.

During both the growth and flowering phases, plants require different nutrient ratios. Within the DutchGrow Hydro line, we provide the plant nutrition Hydro A&B (for the growth and flowering phases). This allows you to give the plant the right mix of nutrients at any time.

DutchGrow Hydro A&B is a high-quality fertilizer, specially developed for the flowering and growth phases of plants in a run-to-waste hydroculture system. It provides all the essential elements the plant needs for abundant growth and flowering. Hydro A&B stimulates fruit formation and contributes to the characteristic taste of the fruits.

Advantages of DutchGrow Hydro A&B:

  • Promotes strong plants with powerful shoots and healthy root growth, which lays the foundation for robust flowering.
  • Can be applied to all types of inert substrates such as rockwool.
  • Ensures a complete uptake of nutrients and water from the beginning of cultivation, thanks to the rich presence of directly absorbable nitrogen compounds and trace elements.
  • Stimulates fruit formation and enriches the taste of the fruits.
  • Contains the right amounts of phosphorus and potassium, and is rich in directly absorbable trace elements, ensuring lush flowering.

Why an A & B nutrient?

DutchGrow Hydro A&B consists of two parts, part A and part B, and these are kept separate for a specific reason. It can happen that when certain elements from part A and B are combined, they clump together and are not absorbable by the plant. Therefore, you should first add the A component and then the B component to the nutrient water.

User manual

  • Shake well before use.
  • Fill the nutrient solution tank with water.
  • Add Hydro A and B (10-35 ml) per 10 liters of water in equal amounts as follows:
  • Add Hydro A to the tank with nutrient solution.
  • Stir well, then add Hydro B.
  • Stir again thoroughly and let the mixture rest for a few hours.

  • For exact dosing values: see feeding schedule.
  • Recommended pH value: 5.4 - 6.4.
  • DutchGrow Hydro A&B Fertilizer can be used in both the growth and flowering phases.
  • NEVER mix the A and B components undiluted as this can cause insoluble compounds to form.
