2 pieces Wall Hanging Plastic Flower Pot

This kind of self-watering pot has a black net filter inside at the bottom of the pot to separate the water and the solid . This filter will leave a certain room for water storage at the bottom of the pot,
And keeps the solid upon the water . And the solid in the water absorbing holes would absorb the water from a long time . The bottom hole could release the extra water when it is raining or watered too much. And a stopper would keep the water from running out of the pot if necessary. The filter could keep a good water balance for the solid and benefit the plants growing on the pot.
