I recently ran across an article in Urban Garden about growth mediums. One section that caught my eye was an article about using silica stone. Results were from the magazine, not the company that produces this product, so it seems to be a viable and accountable article, not slander. Anyway, the article proposed using a 50/50 mix with silica stone and hydroton, which produced a much better root mass and tighter node spacing. Of course this experiment was not done with our subject, I think it was tomatoes. So I was just wondering if anyone have tried/seen this done before and can account for such results.
Also, I did go for the bag of silica stone at the hydro store this past weekend, it was a little more expensive, but not much. So, sooner or later I can produce such results myself. But curious till then if anyone has some experience.
