I hope this isn't a high jack. I've been using Protek for years and have been thinking about switching to silica dioxide https://www.kelp4less.com/product-category/soil-enhancers/silica/
Does anyone have experience with this product? Anyone used both agsil16 and silicon dioxide? I'm definitely switching from protek next purchase. I'm just still unsure what to switch to....
I wonder if it really is plant available?
I can't remember but...
SiO2 is sand and glass...
Seems it would have to be broken down by microbes as well.
