SUPERthrive Pro-TeKt The Silicon Solution NPK 0-0-3 is a nutritional supplement providing silicon and potassium to strengthen plant cell walls, increasing the mechanical strength of stems and enabling the plant to bear heavier buds and flowers. It increases the growth rate of plants and enhances their heat and drought tolerance and supports the plant’s defences against insects and fungal infection. SUPERthrive Pro-TeKt is suitable for use with all types of growing media. It can be used in conjunction with other nutrients but should always be added to the water first before the other nutrients. SUPERthrive Pro-TeKt can be applied by hand-watering, by automatic irrigation, or it can be added to hydroponic solutions. It can be used as a foliar spray on some plants.
