Growth Technology Liquid Silicon 

Silicon is a beneficial plant nutrient, found in virtually all natural soils but not – until now – in hydroponic nutrient solutions. Silicon will strengthen the plant walls producing stronger healthier plants with massive root systems and increased resistance to pests and disease. Liquid Silicon is highly beneficial to plants in the range of 10–30 ppm in the nutrient solution. It is not included, and cannot be included, at these levels, in nutrient concentrates. It needs to be added as a separate component by the grower. Liquid Silicon can be added to nutrient tanks every time a fresh batch is made up.
