Consider it an Apple Watch for your plants for wayyyy less money — sharing a read on your plants’ health via pH level, soil moisture, temperature and light intensity.

This simple, battery-powered soil meter is an easy-to-read tech-y device that’ll assist you in precision plant care both indoors and out. Simply, stab the reader into your plant’s soil and wait under a minute to see insight into your plant’s water levels, acidity, lights and temperature. “You see the information in under 30 seconds… I was very impressed,” one wrote.

The large LCD screen on a bendable head is easy to read, even when outdoors, with quick visual symbols that make reading the data fast and easy, while its 45° rotating head means you can tilt it upwards without having to bend over much to see it. Fans appreciate the digital interface, finding it easier to read and giving more accurate data than their previous analog ones. Even reviewers with years of experience call it an essential gardening tool that ensures more data of your plants than the age-old “eyeball test.”

“This is the year that I am going to grow a successful garden without over/under watering, adding the right fertilizer, keeping enough mulch, etc. I needed a tool that could accomplish that,” one wrote. “Hopefully, this will save me money in lower watering costs and dead plants.”
