Research is one thing yes, but experimenting incredible, I was always skeptical of sio2. Same npk label u showed me. Then browsed for about 2hours until this super smart chemist guy had a web page that explained how to properly use silica, by tonight hopefully I'll find the site. He explained to properly activate it you must use fulvic acid. In 1 gal water ppm no matter how much sio2 read 0. Each tsp of every macro read it's value in separate 1g. Then upon adding 100ppm npk fulvic something incredible happened the ppm read 700. Silica I now understand when activated connects all the microbes on a microscopic level.
