Reply To: Thinking of trying out silica in my next soil grow

I use silica blast every other water. Be sure to add it before nute or it can cloud up and won’t mix properly. It’s actually most effective as a foliar spray, only a small amount gets absorbed through roots.

Although the guy at my shop was telling me about a different type if silica that can be absorbed at a higher rate. It was 60$ for a small bottle so I passed. It was called facilitor.
