Hesi Pro-Line Hydro Growth 1l
Hesi Pro-Line Hydro Growth is a single-component NPK growth fertiliser engineered for hydroponic systems. With proportionally higher nitrogen content than Hydro Bloom, it delivers the nutrient profile vegetating plants require for shoot development, chlorophyll production and root mass expansion. Integrated vitamins and amino acids promote rapid biofilm formation on initially sterile hydro substrates, improving water retention and nutrient accessibility. Stabilised trace elements maintain bioavailability across the full operating pH range. No A+B mixing complexity required. Target parameters: EC approximately 1.5 mS/cm, pH 5.8-6.2. Dosage: 50 ml per 10 litres. Order at plantandflower.be for fast shipping across Belgium.
Hesi Pro-Line Hydro Growth 1l – Single-Component NPK Growth Fertiliser for Hydroponic Systems
Hydroponic cultivation removes the safety net of substrate buffering. Every nutrient must be immediately available in the root zone solution at the correct concentration and ratio. Hesi Pro-Line Hydro Growth is purpose-built for this demanding environment, delivering a complete NPK growth profile with all macro and trace elements in a single-component formulation that eliminates A+B mixing complexity.
Nutrient delivery in unbuffered systems
In hydroponic systems, the nutrient solution passes directly through the root zone without substrate storage or gradual release mechanisms. This means the solution composition at the point of root contact determines the entire nutritional input. Hydro Growth addresses this with a higher proportion of nitrogen components compared to Hydro Bloom, matching the elevated nitrogen demand during vegetative growth for shoot elongation, leaf expansion and chlorophyll synthesis. Complex-binding substances keep all elements in stable, plant-available form in a single solution.
- pH-independent trace element stability: chelated iron, manganese, zinc and copper remain bioavailable across the full 5.5-6.5 pH operating range critical in hydroponic systems.
- Vitamins and amino acids as biofilm promoters: accelerate the colonisation of initially sterile substrates with beneficial microorganisms that improve water retention and nutrient accessibility.
- Single-component convenience: all incompatible elements stabilised in one solution, eliminating A+B dosing errors and reducing reservoir preparation time.
Supporting young plants through hydroponic acclimatisation
Young plants face a unique challenge in hydroponics: limited root mass must absorb sufficient nutrients while simultaneously expanding to provide structural anchoring. The vital substances in Hydro Growth bridge this gap by supplying metabolic energy through pre-formed amino acids and vitamins that bypass the plant's own synthesis pathways. Once roots establish and the substrate develops a healthy microfilm, the plant transitions into rapid vegetative growth. Maximise this critical establishment phase by combining Hydro Growth with Hesi Roots from the first day of system introduction.
Operating parameters and bloom transition
Apply 50 ml per 10 litres in the nutrient reservoir. Target EC during the vegetative phase is approximately 1.5 mS/cm at a pH of 5.8-6.2. Monitor these values frequently – hydroponic systems lack the natural pH and EC buffering capacity of soil, making regular measurement essential. When plants signal flowering onset, replace the reservoir solution with Hesi Hydro Bloom. From mid-bloom, supplement with Hesi PK 13/14 to progressively increase phosphorus and potassium without risking excessive PK levels during early flowering. The orange colour code on the Hesi packaging instantly identifies hydro-specific products within the range.

What dosage of Hesi Hydro Growth should I use?
Apply 50 ml of Hesi Hydro Growth per 10 litres of water in your reservoir. After mixing, verify the EC value which should reach approximately 1.5 mS/cm during the vegetative phase. For very young plants recently introduced to the hydroponic system, start with half dosage to avoid nutrient stress on undeveloped root systems.
What is the difference between Hesi Hydro Growth and Hesi TNT?
Hydro Growth is formulated for hydroponic systems where all nutrients must be immediately available in ionic form. TNT Complex is designed for soil and coco substrates that provide buffering and gradual nutrient release. TNT uses organic nitrogen that requires substrate-mediated breakdown – a process that does not occur in hydroponic media. The two products are not interchangeable.
What pH and EC should I target with Hesi Hydro Growth?
Target pH 5.8-6.2 and EC approximately 1.5 mS/cm during the vegetative phase. These values may vary depending on source water quality. Monitor both parameters regularly as hydroponic systems have no natural buffering capacity. Adjust pH with appropriate correctors if readings fall outside the target range after adding Hydro Growth to the reservoir.
When should I switch from Hydro Growth to Hydro Bloom?
Switch to Hesi Hydro Bloom when plants show the first flowering signals or when you adjust the photoperiod to 12/12. In hydroponic systems, the transition can be immediate because there is no substrate buffer holding residual growth nutrients. Drain and refill the reservoir with the new bloom nutrient solution for a clean changeover.
