The copper in Harvest Miracle stimulates an existing enzyme in plants that enhances the availability of iron—a crucial ingredient in the production of chlorophyll, the pigment that makes plants green. That in turn allows plants to absorb more energy from the sun—and grow, grow, grow! Easy to apply throughout the entire grow cycle and through to harvest. The active ingredients in Harvest Miracle are natural and clean, and serve as a natural defence against the chief stressors on plants: pests, fungi and bacteria. Delivered through a foliar spray, these elements are formulated in concentrations that disrupt the life processes of stressors, freeing up more of the energy that plants need to flourish.
