Self-watering and deep reservoir: No more annoying wicks that clog and stop working. The hollow legs extend into the reservoir, allowing the soil itself to naturally absorb moisture, preventing its delicate root system from being constantly flooded. This eliminates the common problems associated with other planters and overwatering. Scientific irrigation design: Includes a self-watering insert and a drainage hole on the side. Water enters through the small side holes and is stored in the reservoir, where plants automatically absorb moisture and nutrients.
