While not considered an essential element for most crops, silica helps virtually all plant species on the planet by supporting strong cell wall development.  Rigid cell walls are crucial for tolerance of abiotic stress such as heat and drought, which prevents wilting and ensures strong plant performance.  With two sources of potassium (potassium silicate and potassium chloride), Pro-Silicate adds the nutrients necessary for improved flowering and fruiting. 
 
Use Pro-Silicate during vegetative and reproductive growth. Watch pH as Pro-Silicate is a strong base.
