Optimum Hydroponix Silicate 0-0-3 is an easy to use liquid formulation of potassium silicate (K2Si) which is to be added to a final pre-mixed nutrient solution to provide supplemental silicon and potassium.


Applying silicon has been shown to enhance plant growth and increase tolerance to environmental stresses such as cold, heat or drought-like conditions by helping to reinforce plant cell walls. Especially useful in hydroponic applications where adequate supplies of silicon are not readily available.
