i bought a 3rd humidity meter which is also not matching the others in humidity, i will still use the black one for the readings, i will probably just leave all 3 there for the remainder of the grow
also i haven't been using the dehumidifier as it isn't needed yet
it's fairly close to dry enough for grovebags and tested and it's really good and i can tell it will be far better with a cure so if considering getting it i recommend, i will grow it again for sure :)
