“Many busy professionals want to have plants in their home, but don’t have the time to maintain them. This self-watering planter maintains the plant by itself, requiring only a tank refill every other week. It waters the plants when the soil is dry, turns on the lights when the room is dark but the owner is awake and away, and signals when it runs low on water.
