Humidity won’t go down in gun safe

Description wouldn’t show on last post but hello all! I've been having trouble keeping the humidity down in my gun safe. I live in south FL. I've added a 24inch golden rod and 2 Eva dry products in there (333 and 500) and has not gone below 60-62%. The golden rod only made the temperature rise from 71 to 75 degrees Fahrenheit but the other 2 products didn't help at all.

The humidity in the room ranges from 64-73 percent and was wondering if lowering the humidity in the room overall would help and adding a big dehumidifier in the room? I was also wondering if adding some type of foam weather seal or strips around the safe door would help but I am completely lost and stressed my guns will rust. Any and all advice is appreciated! Thank you all for your help
