Pythoff is a broad spectrum disinfecting agent that will sterilise your entire hydroponic system to ensure maximum plant performance all year round. Probably the best disinfecting agent for hydroponic use.
Pythoff is based on monochloramine - it is a non toxic and long lived disinfectant. Being a long lived disinfectant is beneficial for hydroponics because this enables completesystem disinfection - from the nutrient tank all the way through to the plant's roots.
Pythoff is non systemic and therefore it can be used throughout the fruiting period.
DOSE: 1 to 2 ml per 10 litres of water. Super concentrated.
