Vansil W-20 Wollastonite (Ca₂O₄Si), 50 lbs 6 inch These fans have 90° oscillationWollastonite is a natural calcium silicate mineral. VANSIL wollastonite is sourced domestically and is not chemically treated. Because it is milled natural ore, elemental analysis can show natural minor variations. Research has shown plants supplemented with silicon have increased yields, even in prime growing conditions. Supplemental silicon strengthens plant cell walls and improves resistance to insects and disease. Silicon also stimulates plants
