Whether it's your first fern or the latest in a growing collection, staying on top of every watering schedule takes more than good intentions. The La Crosse Technology 919-147 Digital Plant Care Watering Timer with Temp and Humidity supplants the guesswork with two built-in watering modes. Count-Up tracks days since your last water—increasing every 24 hours—while Count-Down lets you set a custom reminder from 1 to 45 days and alerts you when it's time. Built-in temp and humidity readings round out the picture, and the compact color display fits right on a shelf or hangs nearby. A simple way to hedge your flora bets. | La Crosse Technology | | Digital Plant Care Watering Timer with Temperature and Humidity | White | Best Buy
