Dechlorinating Gard'n Gro garden hose filters are a great way to promote healthy plant nutrition and growth by returning the natural balance to your soil, compost, or mulch. Organic farmers and gardeners have known for years that a wonderful way to protect their plants and the environment from insects, disease, and pests is through the use of beneficial bacteria. The healthier a plant is, the more likely it is to resist pests and disease. Unfortunately, highly chlorinated water used by the municipal water supply to eliminate contaminates often kills the microorganisms in the soil that are there to protect the plant and help produce the plant's source of food. Our Gard'n Gro garden hose filters effectively removes over 85% of the chlorine from garden hose water to bring the goodness of Mother Nature back to your garden.
