Optimum Hydroponix Silicate MAX 0-0-8 is a concentrated jelly form of potassium silicate (K2Si) which is to be added to a 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.
