Silica is one of the micro minerals necessary for the proper development of your plants. Normally these micro minerals are all included sufficiently in your base nutrients, but more and more research is showing the positive benefits of supplementing extra silica for cannabis plants in particular. Silica acts as the "cement" in your plants cell "walls", supplementing extra silica encourages stronger cell walls or more sturdy, thicker stems and branches and darker leaves, a by product of this is more resistance to environmental stress and pest pressure, as well as faster growth and overall increased plant health.
