when learning what to do with that moisture meter it should be noted that with its inaccuracy there is only one real measurement that it can do. Sticking the probe in the soil usually results in a "moist" reading, but if you continue to go deeper and deeper with the probes, the meter will suddenly peg over to the right side, saying "WET". You have just found the water table. Imagine a small lake in your container who's level continues to drop as the plant uses the water. The top of that water table acts like a diaphragm to pull oxygen deep down into the soil, and it is important to let the level of that water table to fall into the last inch or so of the container before watering again. Yes, sticking the probe in from the bottom will tell you if moisture is down there, but it won't tell you where that line is. Track that wet/moist line as it falls each day and you will get a good idea of the water use of your plants, and you will be able to project ahead as to when the next time you will water should be.
