Hi The red light inside my digi is off after about 12hrs and the RH is around 45 is that normal? The red light inside my cabi is no longer there because last night it was still on.
According your initial post it's already there. No need to be 'anal' about the percentage, if a range is given then any value within the range is a valid one.
I suggest you get another digital hygrometer to test the RH. I found both the analogue hygrometers in my Akarui are not accurate. I had to do the salt test and adjust the hygrometers accordingly.
