How clever and inconspicuous—a water indicator disguised as a rock!
Never forget to water your plants again! Wrox is a soil moisture indicator that alerts you when a plant’s soil is becoming dry and needs watering to sustain a healthy plant. This natural looking soil moisture indicator takes away the guess work, letting you know when plants need watering—and just as importantly—when they do not! The 1-inch small rock turns blue when plant has enough moisture and then turns white as the plant starts to dry out. Use the rock over and over again. Can be used on indoor and outdoor plants. Pack of 3 rocks.
