Specially improved Vasso Smart Watering Pot is divided in two parts; bottom chamber is filled with water whereas the top chamber is filled with soil. Bottom chamber under the top soil chamber has a different water capacity according to the size of the pot. If you fill the bottom chamber with water, you won’t need to water your plant for a long time according to the plant type and ambient temperature. The moisture-maintaining property of Vasso Pumice stone which stays just a few centimeters under the soil provides water to plants as their need.
