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 extensive experience as water treatment consultants since 1966.

Is safe and non-toxic. This enables dosing throughout the fruiting period and compliance with 'organic' farming guidelines that prohibit the use of chemicals.  Safe to use from seed to harvest.

Compatible with all systems and substrates, but not with hydrogen peroxide or beneficial bacteria.

Easy to use: Pre-dilute with water prior to adding to the working nutrient
