Tierra Garden Moisture Sensor Plant Alarm 2 Piece Kit - Standard 8"l, Tall 10.5"l

The Plant Alarm Kit comes with a Standard Plant Alarm and a Tall Plant Alarm. The award-winning alarms, measuring 8 inches long for the standard and 10.5 inches for the tall, check moisture at the root level and provide instant notifications of the plant's water needs. They flash red when the plant requires water and green when it doesn't. With 80% of houseplants perishing from overwatering, these Plant Alarms help prevent both overwatering and underwatering.
