Resulting in healthier, bigger yielding plants


By vastly increasing microbial activity in the medium, Viresco suppresses fungal diseases such as Pythium (root rot) and has also been found to discourage leaf pests. Viresco corrects nutrient imbalances and improves nutrient uptake and utilisation to such an extent that it is recommended to reduce fertilisation rates by 30%, thereby saving money on costly nutrients. Do not use Viresco with chemical pesticides or fungicides. Viresco contains a mixture of beneficial soil micro-organisms, enzymes, humic acids, fulvic acids, polymers and chelated micro-nutrients.


Viresco Hydroponic each 50g pack should be used in 1000 litres of solution.


Viresco Dry is bulked out with fi ne-grade granular humate, and should be mixed into soil/coco in its dry form; the microbes will become activated once the medium has been watered. Each 300g pack will treat approx. 1500 litres of medium.
