Description Pythoff 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 "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
