Green Planet Nutrients Plant Guard
Plant Guard is a 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.
Add 0.5 ml/L (2 ml/Gal) each time you fertilize in conjunction with your regular feeding schedule. Discontinue 2 weeks before harvest. Dilute Plant Guard separately before mixing with other nutrients.
