High-quality clay: Terracotta watering tips are made of high-quality clay, which has good permeability and weather resistance. When the plant waterers are inverted, the porous material prevents water from leaking from the bottle and allows the water to pass through slowly. The wetter the soil, the slower the water seeps through. When the soil dries, water seeps through the plant watering device.Automatic watering: Drip irrigation has an automatic watering system and is a good helper for gardening. The watering system for potted plants saves your time, and you don't need to water every day. You don't have to worry about unattended plants when you are on a business trip or on vacation.Garden watering device: Delivers water directly to the plant roots, suitable for most houseplants. Easy flow control means your plants receive the right amount of water. You can also add water and fertilizer to one bottle and then use the water spike to deliver the ultimate nourishing liquid.Easy to Use: Say goodbye to self-watering devices that require drilling or cutting the bottom of the bottle. Our self-watering spike system for plants can be installed directly into the soil and can be used without drilling or cutting holes in the bottom of the bottle, which is very convenient.
