Plant Guard 4L

Plant Guard is our potassium silicate supplement used in the vegetative and flowering stages of growth. Silicate increases the rigidity of your plant’s cell walls to support a heavier harvest and increase resistance to environmental stress.

Potassium silicate is a vital element that plants use at the cellular level to build up natural plant defences through cell wall development. Silicate strengthens cell walls for robust stalks and branches that can support heavy fruits produced in the flowering stage. This also means more water and nutrients can be easily transported throughout the plant to promote faster and healthier growth. Rigid cellular development from silicate will increase the plant’s ability to withstand environmental stresses that can come as a result of high and low temperatures. 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. Unused silica accumulates in the outer layer (epidermis) of cell walls to prevent damage caused by pests. Plant Guard ensures that plants grown hydroponically get the optimal amount of potassium silicate to properly build up natural defences.
