Product Description

OSA 28 Plant Available Silicon (as monosilicic acid) strengthens cell walls, increases nutrient uptake, and helps plants handle all kinds of stresses. Other silicates are not bioavailable and take time+microbes to become plant available. This makes OSA 28 the fastest option for delivering silicon directly into the plant cell walls! Silicon also has a synergy with calcium in building better plant structure. Many growers see increased calcium response when feeding with OSA 28.

Silicon is the second most abundant element in the earth's crust. It is now known to be essential for optimal plant growth, health and production. Silicon in the soil isn't available (as various silicates). Plants can only absorb silicon as monosilicic acid (individual molecules). Orthosilicic acid is the stabilized form that transforms into monosilicic acid when mixed in clean water. Silicon chemistry is quite tricky so purity of ingredients and manufacturing excellence are necessary to get a stable and effective product to you.

OSA 28 is manufactured in-house by our staff Ph.D chemists in the USA with domestically sourced ingredients. This means lower cost, fresher product, and more quality control. Monosilicic acid is tricky to make since it requires complex reactions to produce a stable product. OSA 28 is shelf-stable and has higher concentrations than competitive products but at a much lower cost.
