ThirstyLight keeps watch on plants so you don't have to

While it won't keep watch on your plants and water them like some devices we've seen, the so-called ThirstyLight will at least handle one part of that equation, with it sending out a signal in the form of a blinkin' LED light when your plants' soil gets dry. That's handled by a "Drypoint Digital Circuit," which checks moisture levels once per second and is able to discern between five different levels of dryness (relayed to you by blinking patterns of increasing urgency). If that sounds like the solution to your plant problems, you can pick one up now for $10, or get 'em in bundles of three, six, or twelve at a discount.
