How to use: As the soil dries, the ceramic cone delivers water gradually into the surrounding earth, creating a vacuum within the cone that draws water from a nearby container. Once the soil is sufficiently moistened, the watering stake will stop flowing. Note: Close the cap when filling the stake with water to allow proper vacuum formation. Useful tools: Self-watering probes provide a simple and effective way to water plants during vacations, business trips, or when regular watering is missed. Application: This 10-pack of watering stakes is compatible with most automatic garden watering systems. Ideal for seeding and planting, providing a clean and consistent water release into the pot as needed by the plants. Measurement: The connecting tube is 75 cm (29.5 inches) in length, allowing direct water delivery to the roots for efficient drip irrigation. Kindly reminder: Watering stakes are suitable for indoor plants. Ensure the water reservoir and flower pot are placed at the same level. Placing the reservoir slightly higher may enhance the drip irrigation process.
