Nutrivada Gro Guard 4L
Gro-Guard is a special product created to provide additional potassium and silica. For optimum results, use Gro-Guard at the recommended application rate each time you water or fertilize. Add slowly to the nutrient tank to avoid clouding. Using warm water will help dissolve material faster and adjust your PH accordingly after adding Gro-Guard.
