Advanced Phosphorus Fertigation with a Built-In Cleaning Advantage
Phosphorus is essential for plant growth and is commonly supplied as orthophosphate (PO4), which is readily available for uptake. However, orthophosphate tend to react with calcium, magnesium, and iron present in irrigation water or soil, forming insoluble precipitates. These precipitates reduce nutrient availability and cause clogging in irrigation systems—especially in drip lines and emitters.
A common workaround is to increase phosphorus application rates to offset these losses, but this often exacerbates precipitation issues and leads to higher maintenance needs.
Safe Growth and Clean Fertigation
Haifa GrowClean™ overcomes this challenge by delivering phosphorus in a stabilized form. It features a 1:1 combination of polyphosphate and orthophosphate, offering dual functionality:
Polyphosphate prevents precipitation and keeps nutrients in solution.
Orthophosphate ensures immediate phosphorus availability and prevents excessive alkalinity.
This balanced formulation maintains optimal pH levels in the fertilizer solution, eliminates the need for separate acidification, and enhances compatibility with other water-soluble fertilizers.
Built-In Cleaning Effect
Haifa GrowClean™ not only delivers nutrients—it actively cleans your irrigation system. It breaks down existing mineral deposits and prevents the formation of new ones, enhancing system performance and extending equipment lifespan. Clean irrigation lines improve fertilization efficiency and allow for optimized nutrient delivery with reduced application rates.

Ideal for Soilless Fertigation and Hydroponics
Haifa GrowClean™ is especially well-suited for soilless cultivation and hydroponic systems, where fertigation precision and system cleanliness are critical. In these environments, even minor precipitation can lead to significant nutrient imbalances and blockages in narrow emitters. The unique polyphosphate-orthophosphate blend in Haifa GrowClean™ ensures stable phosphorus availability, prevents mineral buildup, and supports optimal nutrient delivery. Its ability to maintain clean irrigation lines and balanced pH makes it a reliable and efficient solution for continuous fertigation, helping growers achieve consistent, high-quality yields in controlled environments.

Application Notes
- Haifa GrowClean™ contributes a significant amount of phosphorus. When only a small phosphorus dose is required, it should serve as the sole phosphorus source in the nutrient solution.
- Dosage for cleaning and maintenance depends on the current condition of your irrigation system and growth stage:
| Recommended dose of P from polyphosphate | Haifa GrowClean™ conc. | Total P |
| 0.25 mmol/l | 11 kg/1000 l | 0.5 mmol/l |
| 0.5 mmol/l | 22 kg/1000 l | 1.0 mmol/l |
