Bio-SuperSil Soluble Silicon Fertilizer (1 Quart) for Plant Growth Soil Health nanostructured Silica hydroponic Gardening Fertilizer Organic

This is the only silicone I’ve tried. Used it all growing season (one bottle only) and my plants are SUPER healthy looking. I probably won’t try anything else, why fix something that’s not broken right :)I also use an all purpose fertilizer and hydro guard but I really do think this silicone is amazing!I did reach out to the company when I first received it bcuz it came with no seal and I was terrified I was using something that would kill my babies but I’m thankful they are ok.

Silica is always one of those products that I can never tell if it’s working or not. What I will say is branch’s were snapping real easy before I started using this. Now not so much.

This is definitely a clear winner over any other silica supplement I've tried. It builds thick, strong stems and helps the plants deal with stress like heat. We had some really hot, dry weather this summer but my plants never seemed to be bothered

Absolutely nothing working as well for Si this year. Clear winner here!!!

works as it should. builds strong stems for plants.

I can use it with no worries and it’s available faster for plants to use

Over the past five years I've tried various SiO2 silica products in my gardens with often no noticeable results. The only one that seemed to work well, or at all, was very expensive. ($89.99/250ml) After a whole summer of using Bio-Ag Super-Sil I can say it's worked just as well for a third of the price. I live on a hill and we're already getting night temperatures in the mid thirtys without any noticeable stress to the plants.
