The automatic pot irrigation system is ideal for watering indoor flowers, outdoor plants, or vegetables during holidays. Provide different amounts of water for different plants and flowers. Easy installation, just connect plastic or glass beverage bottles and place the sprinklers in the pot, then open the control valve and adjust the flow rate according to your needs. Fits most bottles. Our self-watering plant system has an inclined reverse plug-in interface. Our self-watering units are not affected by water pressure and stop dripping, so there is no need to make a hole for bottles.
