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.

  1. Monster Plants 5 Star Review

    Posted by on Dec 29th 2015

    I started using OSA after seeing the pros like OG Raskal and Swamp Boys reppin it hard saying don't grow without this product. I checked it out and was surprised a little by the price tag so I got a free sample. I started using it on my seedlings right away and I been loyal ever since. My plants are extremely thick and vigorous. They can feed like nothing I've ever seen just smashing thru nutrients in beast mode. Maybe I'm crazy but my plants never looked this beast and all I've done was add OSA. Others have noticed as well and have commented to me about the change in size and overall vigor of my gardens. Its def not leaving from my mix ever. I actually haven't foliar sprayed with it yet but Im looking forward to that. I also like how I'm supporting a local business by buying OSA. As long as they keep bottling that shit up I'm gonna keep crushing it in 2016 and you can too and they don't pay me to say this I'm just that impressed!
