FLAIRFORM PYTHOFF 1L 

Pythoff maximises the effective working life of water and nutrient and helps prevent plumbing blockages. Pythoff's formulation is a result of our extensive experience as water treatement consultants since 1966. Pythoff is safe and non-toxic and can be used from seed to harvest ensuring maximum performance throughout. Pythoff is also non systemic which enables dosing throughout the fruiting period and compliance with 'organic' farming guidelines that prohibit the use of systemic chemicals. It is compatible with all systems and substrates however it shouldn't be used with Hydrogen Peroxide or beneficial bacteria. As with all products, it is advisable to test compatibility prior to routine use. 
Simple to use: Pre-dilute with water (2mL per 10L) prior to adding to the working nutrient. The nutrient pump then delivers Pythoff throughout the whole system.
