"For 20 years we had crop failure every year, especially in summer. Since we started using Pythoff four years ago, we have not lost a crop"
Commercial grower with 50,000 plants

pythoff 250Pythoff maximizes the effective working life of water and nutrient, and  helps prevent plumbing blockages (e.g. drippers, jets, filters, pumps).
Pythoff’s formulation is a result of our extensive experience as water treatment consultants since 1966.

  • Pythoff is safe and non-toxic
    • Non systemic: This enables dosing throughout the fruiting period, and compliance with ‘organic' farming guidelines that prohibit the use of systemic chemicals.
    • Safe to use from seed to harvest:   Ensures maximum performance throughout.
  • Compatible with all systems and substrates
    * Note, Pythoff is not compatible with hydrogen peroxide or beneficial bacteria.  As with all products it is advisable to test compatibility prior to routine usage.
  • Easy to use: Pre-dilute with water prior to adding to the working nutrient. The nutrient pump then delivers Pythoff throughout the system.
  • Multilingual labell
