Dont make the mistake above. I also got one that measures luminosity, moisture, and ph. In my opinion only the moisture is accurate enough to be any help. These moisture meters are less than five bucks and are all you need to measure moisture at the bottom of your pots. The things are great to have because you dont want to over water and get root rot. Its hard for me to imagine how they work, but put it under water and you'll see it tell you its wet. Accurate enough :thumbsup:
