Whether you’re a perfect plant parent living in an indoor jungle, or just starting your plant collection and journey, a moisture meter is the perfect addition for your plant needs. Ideal soil test tool kit for house plants, garden, lawn and farm. This moisture meter measures the level of wetness between 1 - 10. Level 1 means very dry, and level 10 means very wet. No plants can tolerate the two extremes for long, so it is important to often check on all of your plants.
