Keep your plants looking their best with the Water From a Stone Plant Watering System. This slow draining system actually houses 7 ounces of water in each “stone.” Thanks to some pretty clever design features, the Water From a Stone allows water to slowly seep into your plants and soil. As a result, you can maintain a fresh flow of water. In fact, the Water From a Stone can take up to four days to fully drain so you don’t have to worry about your plants for days on end. In addition, the Water From a Stone is made from stunning hand-blown glass. Unlike other bulky systems, it fits right in with your plant as it showcases the water with its transparent design.
