The upside-down flowerpots will bring green to your home and to your workplace, without sacrificing any floor or table space. The Sky Planter has an innovative Slo-Flo irrigation system. With the Slo-Flo container you will be able to water the plant without spilling any water on the floor. The Slo-Flo also makes sure that the plant does not need to be watered that often, Slo-Flo will water the plant for a long time. You will know when it needs to be watered again if the green indicated on the top of the pot is down.
