Best Overall Soil Meter
The epitome of simplicity and that's one of the reasons we love this. We tested it on various types of soil and dampness levels, and it responded accurately.
Use the 10 point scale to monitor the soil or use the quick read color-coding on the dial. Red for dry, green for moist, and blue for wet.
We inserted the meter probe into the soil, no calibrating or prep necessary, and the dial gave an immediate reading. It offers accurate readings, and the probe is securely attached. It also doesn't require batteries or charging, making it ready to use right from the box.
The sturdiness and ease of use of this 3 in 1 Soil Meter by Vigoro make it a winner in our book.
