So, 58% is too high for you? I also run a semi-sealed room but with a window unit, in a high RH area I CANNOT get away without a dehu or my lights off rh can creep into the mid 80's.
58 is with the duc/filter off, when is on it goes up to 75-80
now is 40* humidity outside 80

it looks like you live in a humid area .. is that cold/humid or hot/humid ?
and i guess you have this problem during lights out ?
because 70 % rh during lights on is good for bloom, as long as your temperature is in adequation .. ( around 80f for 70% rh )

humid hot area outside, i got the problem only with ducting/filter on, ligths on or off i get 40%-50% 24-27c nigth-day temp
