100% natural silicate powderT.A's silicate comes from old deposits and is very similar to their old version, however, there are a few advantages to their new one. Even higher content of silicateSmaller particle size, gives better solubility and therefore easier for the plant to absorbContains more carbonate, for better pH stabilityProvides calcium to your plant 100% natural silicate powderDeposits of biologically transformed organic matter plus naturally formed Silicate is an essential element for tall plants, especially when grown in hydroponic systems without soil/coco.This new pH neutral silicate contains prehistoric deposits of biologically transformed organic matter, plus naturally formed silicic acid clay. Silicate adds a natural and absorbable form of silicic acid, which is absorbed by the plant's cells and thereby helps to build a shield against diseases and insect attacks. Natural colloids improve the cation exchange capacity of the fertilizer water, which improves nutrient availability to your plants. You thus ensure optimal conditions for your plants!
