Features: Self watering pile - our watering pile will automatically release water slowly. If the dirt around the stake dries, water will automatically suck into the dirt from the ceramic core. In addition, water will continue to suck into the soil until the soil is saturated with water, or until the water level in the bottle is lower than that of plants. Easy to set - first, remove the cover and fill the ceramic pile with water and immerse it in a bowl of water for 15 minutes. At the same time, you can find a bottle full of water. After 15 minutes, insert the stake into the flowerpot and the plastic tube into the water bottle. The self pouring water volume is controllable - ensure that the water bottle is higher than the flower pot, and the self pouring pile will start to work automatically. You can control the amount of water you pour by placing the kettle at different heights. The higher the water bottle, the faster it will be watered, and vice versa. Convenient - for those who like plants but are busy in daily life or often on business, our holiday plant waterer is your ideal choice. Durable - our automatic plant watering nails are made of high quality ceramics with good permeability. The watering pile has weather resistance, so it is durable enough to be used for a long time.
