powerful concentrated silicic acid product formulated to improve plant structure, promote cell wall strength and increase your plants ability to withstand environmental stress. It is 100% soluble and is compatible with all growing mediums. In nature, microbes in the soil slowly break down silicon into a plant-available form known as Monosilicic Acid, but in a controlled garden environment this key element is often missing. Chemboys Silicon Shield feeds bio-available Monosilicic Acid right to the plants roots and allows them to thrive.
