Average Reviews:
(More customer reviews)I'm terrible with houseplants. I received one of these as a gift, and for two years it's been keeping my plant alive - never even had to change the battery. I'm looking to buy a second one.

Hydrofarm HGTL/HGTLF Thirsty Light Original Digital Indoor Plant Moisture SensorTake the guesswork out of watering your potted plants with the Hydrofarm Thirsty Light Original Digital Indoor Plant Moisture Sensor. When a plant's soil becomes dry, the LED on the Thirsty Light blinks to let you know. The sensor head measures just over 2-inches long, so you won't even know it's there until it starts blinking. You can leave the resilient sensor in one pot, or use it to periodically check moisture levels in all your indoor pots--it tests conditions in one second, providing fast, accurate reads.
LED Alert Tells You When to Water PlantsThirsty Light continuously monitors the condition of the soil in your potted plants, testing the moisture level once every second. The senor top features a small LED light that flashes once it's time to water your plant. While the sensor measures a total 6.5 inches, the green top is a mere 2-inches long, so you won't notice it until the soil becomes dry.
By letting you know when your potted plants need water, Thirsty Light eliminates the temptation to overwater plants. A comprehensive user and watering guide is included.
Light Blinks Faster as Soil Becomes DryerThis sensor uses Drypoint technology, which can sense five different levels of dryness. As the soil gets dryer, the light blinks faster, letting you know how urgent the need for water is becoming. The included moisture signal chart explains each blinking pattern, as well as where to properly insert the sensor's probe.
The sensor also has a unique blinking pattern to indicate when the batteries are low.
Resilient and Long-Lasting ProbeThirsty Light features an ABS plastic casing and a durable brass probe. With constant use, the probe will change color and develop a patina, which simply helps protect it from corrosion. If left in soil for long periods of time, simply wipe the probe with a damp cloth to remove mineral deposits.
Product and Warranty InformationThe Thirsty Light is backed by a manufacturer's 30-day limited warranty against defects in materials and workmanship. It's powered by two included 1.5-volt lithium batteries that can be replaced when necessary.
