Pythoff is an advanced, full spectrum sterilising agent designed to identify and eliminate harmful pathogens in your hydroponic growing systems. Thanks to its unique formulation Pythoff mixes into your nutrient solution and remains active much longer than other inferior competitor products. This means Pythoff has an extremely high success rate in both the treatment and prevention of harmful root born diseases such as pythium infections that can potentially damage or even destroy your valuable plants if left untreated.

Please note: If Pythoff is used in conjunction with beneficial bacteria or fungi based organic products it will identify them as harmful pathogens and neutralise them. We strongly recommend you do not attempt to use Pythoff with any such products.
