I've discovered in my reading that a sealed bag of filament can require drying to provide acceptable prints. If I have advance notice on a print, I'll put a new spool in the dehydrator for an overnight stint. After the print is done, it goes into an Eibos vacuum bag with a canister of desiccant before it goes on the rack for storage. Sometimes the bag leaks a bit and the desiccant comes out used up, but it still provides protection. Florida here too but the A/C keeps the house about fifty percent humidity, the desiccant does the rest.
