One of the most common reasons our plants don't survive is because we overwater them. Controlling the watering of some of them is not an easy task, especially when they are small and require more care to avoid waterlogging. That's why we've brought you this cool gadget, a watering meter that allows you to monitor your plants from day one. Its operation is very simple. You just have to insert it into the soil up to the marked line and then water the pot. After that, you should wait about 3 hours (the time will depend on the size of the pot. The larger the pot, the longer it will take) until the top indicator changes from the original white color to blue. This will indicate that the plant has enough moisture, and you won't need to water it again until the indicator turns white again. This meter is recommended for 9cm pots.
