Knowing when to water your plants can be challenging especially when you are just getting to know a new plant. The best way to make sure you aren't over-watering or under-watering a plant is to test the actual moisture content of the soil. How does it work? Our meter has a bi-metal probe that gauges the conductivity of the soil to measure the moisture content, indicated by readings from 0 to 10 on the display. By Plant Vitamins.
