Silicon (Si) helps plant to grow. Benefits of silicon include the following:

increases nutrient uptake for better growth and yield, improves plant strength and reduces node spacing, resists biotic (pest, mildew) and abiotic (heat, drought) stresses through the formation of phytoliths.

Silicic acid is the form of silicon that can be readily taken up by plants. Other forms of silicon, such as silicate, tend to be polymeric and not available for plant absorption. All Si28 products contain stabilized silicic acid compounds to provide you with bioavailable silicon.
