Growth Technology GT Silica kit Perlite is a natural occurringINTRODUCING GROWTH TECHNOLOGY GT SILICA Silicon is the second most abundant element in the earths crust making up a component of most rocks. Plants absorb silicon from silica that has dissolved into the soil water. As you can imagine the concentration of silicon in soil water is not that high because rocks do not tend to be all that soluble. Silicon concentration in soil water generally does not get above 20 ppm and this is the level we recommend for
