【High-quality terracotta clay】The plant watering devices are made of high-quality terracotta clay, which is durable, has good permeability and weather resistance. The porous material prevents water from leaking out of the bottles when the plant watering spikes are inverted, allowing water to pass through slowly. The wetter the soil, the slower the infiltration. 【Precise and efficient】When the potting soil is dry, this spike will drip gradually and precisely. When the soil is sufficiently moist, the dripping will stop automatically. You can also add liquid fertilizer to stimulate growth. 【Easy to Use】The self-watering plant watering spikes are designed to work with long-neck bottles, such as wine bottles and beer bottles: simply fill a bottle and insert the terracotta watering can into the soil, fill the bottle or wine bottle with water, connect the bottle with the spikes and turn it upside down. 【Enjoy Your Vacation】Enjoy time with your family, your plants leave me.
