Had my dry cabi for more than a year already. Standard reading everytime at 45 or 46. But since last week with on-going haze, I was having problem with it.
Before the haze, even when I opened the door for awhile the hydrometer will easily read above 58%, now even when I open for few minutes only read around 55%
The humidity drop to 42 and sometimes back to 45...yes during last sat when haze was real bad, reading maintain about 42 to 43 average
Finally itchy hand go adjust the knob...
