With a high concentration of soluble silica, Pro-Silicate™ was developed for strengthening plants grown in soilless media and hydroponic systems devoid of this element. While not considered an essential nutrient, plants accumulate silica in macro proportions for good reason. Plants use silica to strengthen cell walls, resulting in greater cell integrity and stronger stems.   Fortifying cell walls with silica helps plants tolerate stress and be more resistant to attack.
