Comprehensive information

DutchGrow Hydro A&B.

During both the growth and flowering phases, the plant requires a different ratio of nutrients. Within the DutchGrow Hydro line, we offer plant nutrition Hydro A&B (for the growth phase and flowering phase). This allows you to give the plant the right mix of nutrients at any time.

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

Benefits of DutchGrow Hydro A&B:

  • Promotes strong plants with vigorous shoots and healthy root growth, which forms the basis for a powerful bloom.
  • Can be applied to all types of inert substrates such as rock wool.
  • Guarantees a complete uptake of nutrients and water from the beginning of the cultivation, thanks to the rich presence of immediately 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 trace elements that are directly absorbable, ensuring lush blooming.

Why an A & B nutrition?

DutchGrow Hydro A&B consists of two parts, part A and part B, and these are separated 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 nutrient solution tank.
  • Stir well and then add Hydro B.
  • Stir again thoroughly and let the mixture rest for a few hours.

  • For exact dosage values: refer to the 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. This may result in insoluble compounds.
