Plant Guard is a potassium silicate supplement that is used in the vegetative and flowering stages of growth. Plant Guard increases the rigidity of the plant’s cell walls to support heavier plant growth and harvest and aids in the protection against environmental forces.

As the plant uses silica to build up cells, it becomes harder for pathogens such as rust and powdery mildew to enter and damage the plant. Any unused silica will form around the outer layer of the cell walls to prevent damage caused by pests.
