Plant Irrigation Control Device, 5-Pack to Prevent Wilting.

Dimensions: 1 x 0.7 x 12 cm (small) – fits 2, 2.5, and 3-inch pots – ideal for small succulents. The Sustee Aquameter is a self-cleaning soil moisture sensor that, unlike other hygrometers that must be removed after each measurement, remains in the soil for continuous measurement.This set contains five refillable Sustee Watering Sticks (green) – indoor plant hygrometers with refills – each stick lasts approximately 6 to 9 months. This soil moisture tester has a color indicator that shows the water quality for the plant based on the soil type: white means the plant needs water; Blue means it has already been watered. The design and functionality of the stems have been improved.
