I leave the dehumidifier running and at 58-60%. The buds will still have some moisture in them, here on the east coast I can leave them in for about 3 months before they fall lower than 58%, I don’t open the door to the cooler often though. If the cooler is in an environment that is below 58% rh and you open the door frequently that will change obviously, and once the cooler starts dropping below 57% or so I’d put a damp sponge in or bag/jar them up, but if the door is left closed and ambient rh is above 58% it shouldn’t be an issue.
