Thank you for this question. We do not know of any other companies that are cleaning gold mine tailings and delivering an organic, bioavailable silica for plant growth. The gold mine tailings that we're cleaning is a unique geology which is not available at every gold mine. What makes Harvest Gold Silica is that it not only has bioavailable silica, but nine other naturally occurring nutrients that support plant growth. Today, it seems every manufacturer has a silica product. If you take a close look and compare labels the majority of these silica products are just a simple soluble silicon dioxide – derived from a synthetic potassium silicate in a laboratory – in a liquid form. There are others out there made up of volcanic ash, rice hulls, etc. but again, these silica's don't provide nutrients. Harvest Gold Silica is triple action product that provides silica, nutrients and water retention - this recipe accelerates plant growth.
