【Easy to Add Water】There is a concave design at the bottom of the upper flowerpot for injecting water. So you can easily add water from the kettle without having to always lift the flowerpot. Don't worry about water and soil spilling on the ground, it is more convenient to add water while maintaining air circulation. Be careful not to water your plants above the maximum waterline, or you may overflow the water and give your plants too much water. 【Auto Watering】The two-tier pot design can store water in the lower part and keep the soil moist by absorbing water through cotton ropes. You can put an end or both ends of the cotton rope into the water according to the needs of different plants, so as to avoid the trouble of over-watering or lack of water. Adding enough water once can provide your plants with water for 10 days or more, so you don't have to worry about water shortages even when traveling or business trips. 【Highly Transparent Material】The flower pot is made of high quality AS plastic, which is formaldehyde-free, non-toxic and durable.
