Is silica actually useful for plants? 

Silica should be used for plants growing in a hydroponic system during all stages from seedling to harvest. While silica is more effective in hydroponic setups, it doesn’t mean that it cannot be used in soil growing.  

You can use silica both as a foliar spray and a root feed. Experts recommend using it as a foliar spray because it enhances a plant’s absorption ability. It is important to remember that it increases the pH of the plant, and should be applied as the last nutrient.
