Bleh! Moister meter!!! Why waste money on junk? Someone not to long ago wasted money on that shit and was relying on the unaccurate readings it gave and stressed his plant out. Whatever happened to common sence? When the soil is dry the pot will feel light. When it still has water it will feel heavier. Also to check the soil ph is just getting the soil runoff and checking that. That's way way more accurate and it costs nothing, givin that you already have a must have item "ph meter"
