Thirsty Light sensor for plants

The Thirsty Light is a pretty interesting contraption as this $10 sensor helps you be aware of when your plants need some water. Whenever the soil goes dry, it will start to blink like crazy in order to attract your attention. If you find it too much of a hassle to purchase one for every single plant, you can always opt for the “quick check” method that involves you sticking this in all of your plants one after another, with a watercan in one hand. You can choose to pick up a dozen of these for $84.
