Leaf and Flower Molds, particularly Powdery Mildew and Botrytis (aka Bud Rot) can cause untold damage to a growers' crop. Even worse, it can be difficult to spot an infestation until it's too late and it has already devastated a huge amount of fruits or flowers. Keep fungal infections in your hydroponics grow at bay by using a silicon additive in your feeding regime, and by using one of our quality mold control products as a preventative. Also keep relative humidity (RH) below 65% at all times.
