The HealthyWiser 3-in-1 Soil Meter is three meters in one device. With our soil pH meter you can check moisture, light and pH levels in your soil. This easy to use meter is compact and works for both indoor and outdoor plants, veggies, flowers and lawns. Which saves you time, money, and effort because healthy soil produces healthy plants that resist insect damage and disease. For example, without knowing the pH level of your soil you can easily waste money on amendments that you don’t need. You may also be over watering or under watering your plants and unknowingly damage the root system of your plants. Without the proper amount of light your plants will also suffer.
