Plant Watering AlarmAlways forgetting to water that one plant around the house? Our Plant Watering Alarm will let out an audible chirp to remind you when a plant needs more water. Simply insert the battery that comes included, push the meter into the soil, press and hold the button to set the "dry" point, and water! The chirp will sound when the soil reaches the dry point you set. It's that easy! Indoor use only.
