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

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.

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.

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