This moisture meter tells you when to water your houseplants, potted plants or container plants. It blinks when your plant is thirsty and blends in perfectly.

The Thirsty Light is a digital plant moisture sensor designed to be unobtrusive when left in the soil of a plant where it continuously monitors conditions, testing the moisture level once per second. The Thirsty Light blinks a LED light to alert the user when it's time to water. The Thirsty Light has 5 levels of sensitivity and makes the LED blink faster as the soil gets drier.

With the Thirsty Light, you'll never have to guess when your plants need watering and you won’t forget to water your plants because the blinking light will remind you.

The most convenient way to use the Thirsty Light is to leave it in a plant’s soil and let it continuously monitor soil conditions. Place one in each plant so you can easily tell which plants need watering. Read more how to use it.

Tips on how to water houseplants or potted plants

Watering potted plants can be tricky as potting soil dries out easily. The Thirsty-Light simply blinks when your plant needs to be watered; is thirsty Here are some helpful watering hints for the best results with potted plants:

  • Pour water evenly over the surface of the soil until it comes out of the drainage holes.
  • Avoid using softened water.
  • Don't allow plants to sit in standing water for more than an hour.
  • Potted houseplants should always have good drainage. Occasionally the pot's drainage hole can become clogged by roots. Check the hole by pushing a stick or pencil into it.
  • A plant in an unglazed pot will need watering more often than a plant grown in a plastic or glazed pot, as water evaporates through unglazed surfaces.
  • Plants require less water in the winter or dormant months.

Adjusting the thirsty-light in a potted plant or house plant

how to adjust the thirsty-light in a potted plant

It is easy to fine tune the function of the Thirsty-Light to match a specific plant's moisture needs. Soil dries from the top down, so the depth of the sensor affects the timing alerts. If the plant is wilting from lack of moisture between waterings, choose a new location and insert the probe only 2"-3" (5-7.5cm) deep in the soil. If the Thirsty-Light is alerting too soon, push the probe deeper into the soil. Do not allow the pod to come in contact with the soil.
