Thirsty Light Original

The Thirsty Light is an intuitive digital plant moisture sensor that blinks an LED to alert the user when it is time to water a potted plant. It is 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 circuit that drives the device, called Drypoint, can sense 5 different levels of dryness, causing the light to blink faster as the soil gets dryer, increasing the urgency of its call to action, until it reaches the fifth level, “completely dry”, which puts the device in standby mode to conserve electricity, emitting a double blink every 3 seconds. There is a low-battery mode as well: a slow triple blink. The Thirsty Light comes with a comprehensive and informative user and watering guide, and is backed by a 30 day manufacturer’s warranty.

Awesome Product!

"I love the Thirsty Light Ladybug! I have about 50 houseplants around the house and each of them require different amounts of water. Sometimes I over-water, sometimes I under-water. Each plant may also have different soil densities, which makes watering correctly sometimes difficult. The Thirsty Light Ladybug solves that issue - it can tell me if I need to water a little, a lot, or not at all! Great product!"

Little Thirsty Light bugs are awesome!

"I love this little bug. You can get it in butterfly or bumblebee models also. It's small so doesn't take up a lot of space in the pot. I put it into a dry pot and it told me right away to water. I watered, the light went off. It came back on a few days later to tell me the soil was getting dry again. You can move it from plant to plant to check water status. It's really cute and ladybugs are one of my favorite insects, so this fit in with my decor as well."
