It has been estimated that powdery mildew, mold, leaf dwelling insects and leaf dehydration account for over 50% of clone death every year. Clone Guard locks in water molecules from escaping from the leaves preventing the clone from wilting. At the same time Clone Guard is locking out insects, powdery mildew and mold, denying them the access to the clone. Spray or dip clones and always apply Clone Guard to plants before you allow them into your garden.
