GT Silicon is a concentrated mixture of silicic acid and potassium hydroxide designed to add the beneficial nutrient silicon to hydroponic nutrient solutions or when watering plants in soil. It is specifically formulated to strengthen plant cell walls and become a barrier against water loss, fungal infection, particularly mildews, and insect and mite attack. With regular use plants can increase their resistance to pathogens, resulting in healthier and stronger growth.
When added to hydroponic nutrient solutions at a rate of 1ml per litre of nutrient solution, GT Silicon provides a concentration of 20ppm the recommended level for hydroponic systems.
It is important to note that silicates are very alkaline and care must be taken with its use. Always check the pH after silicon has been added to the tank and adjust if necessary.
