IONIC Hydro Grow 1L – fertilizer for hydroponics during the growth phase

IONIC Hydro Grow by Growth Technology is a specialist liquid fertilizer intended for use during the vegetative growth phase of plants grown in hydroponic systems and soil-less cultivation. The formula was developed to provide a complete set of nutrients necessary for vigorous green growth and proper root system development.

The fertilizer formula contains macro- and micronutrients, including calcium and micronutrients in EDTA-chelated form, which remain readily available to plants in a water-based environment. The use of nitrogen in two forms - nitrate and ammonium - enables stable plant nutrition during the period of dynamic growth.

The product also supplies phosphorus, potassium, magnesium, sulfur and boron, supporting the development of leaves, shoots and the root system. The liquid concentrate makes it convenient to prepare a nutrient solution for hydroponic reservoirs and recirculating systems.

Composition and NPK analysis

NPK ratio: 3.3 : 1.2 : 5.4

  • Nitrogen (N): 3.35%
    • nitrate: 2.95%
    • ammonium: 0.40%
  • Phosphorus (P₂O₅): 1.17% (0.51% P)
  • Potassium (K₂O): 5.37% (4.46% K)
  • Calcium (CaO): 1.40% (1.00% Ca)

EDTA-chelated micronutrients:

  • Copper (Cu): 0.002%
  • Iron (Fe): 0.040%
  • Manganese (Mn): 0.010%
  • Molybdenum (Mo): 0.001%
  • Zinc (Zn): 0.0025%

Additionally contains:

  • magnesium,
  • sulfur,
  • boron.

Uses

  • hydroponic systems,
  • all soil-less cultivation,
  • the vegetative growth phase.

The fertilizer is intended for use until flowers appear. It is then recommended to switch to IONIC Hydro Bloom, intended for the flowering phase.

How to use

  • Dilute 7 ml of fertilizer per 1 liter of water,
  • mix thoroughly - preferably in a reservoir with the pump running,
  • use throughout the entire vegetative growth period.

Recommended solution parameters:

  • EC: 1.5 – 2.2 mS/cm
  • pH: 5.5 – 6.2

How does IONIC Hydro Grow work?

The balanced formula supports vigorous leaf and shoot development while supplying nutrients necessary for the proper functioning of the root system. The presence of calcium, magnesium and micronutrients helps maintain stable plant growth in a hydroponic environment, where the composition of the nutrient solution is crucial to crop health.

EDTA-chelated micronutrients increase the availability of nutrients, while the carefully selected proportions of nitrogen, phosphorus and potassium meet the requirements of plants during the growth phase.

Safety and storage

  • causes serious eye irritation,
  • keep out of reach of children,
  • wash hands thoroughly after use,
  • wear eye protection,
  • in case of contact with eyes, rinse with water for several minutes and continue rinsing after removing contact lenses,
  • if irritation persists, seek medical advice,
  • store at temperatures above 6°C.
