Have a new safe in a new house and it’s in the garage. I run a dehumidifier in the garage, a goldenrod in the safe, and a 750g desiccant canister in there as well. Humidity according to my hygrometer ranges from 40-45% throughout the day but temps hit 90+.

I know ideal is 70 degrees and 50%. Is my humidity level ok considering the heat or do I need to add more desiccant or another dehumidifier in the garage or what?
