This practical moisture meter helps you determine the optimal watering for your plants. Insert the probe about three-quarters into the soil and immediately read the moisture level: red indicates dryness, green indicates the right moisture, and blue indicates an overly wet soil. This way, you can see exactly when it's time to water. Clean the meter before and after use and do not leave it continuously in the soil. Specifications: * Dimensions: 280 x 50 x 35 mm * Scale from 1 to 10 (red, green, blue) * Recommended use: measure only when necessary, then clean
