Ok so i a plastic tub. The humidty is like two different readings.
Here is a pic. They have been sitting like this for around 2 hrs
There is always a 10% diff in them. Atm flukers says 59 acu rite says 69 (lower due to be opening the lid)
But there is always a difference of 10% in the two :/
I got quite a few holes in it now. Trying to get it to lower. It does a bit but not much
