you might be just fine, but id lower that rh anyways. other than the obvious dehumidifier, i have heard of a few tricks.
1. Get some
silicon packets that you find it electronics packaging and whatnot. I am also not sure who might carry them locally at a store, but i hear its available at hardware stores.
2. Cat Litter. Again not really sure about this one, but ive heard of people spreading cat litter (possibly of a certain type?) on the floor of a drying box (small scale) to absorb moisture in the air.
3.
Damprid. This is a product i just stumbled upon in some other threads. No idea how well it works or even how it works, as i didn't want to sit through the cheesy vids on their site lol.
i would have included rice with that, but i think the point was across on the kind of thing you would be looking for when going down that road. I am betting those silica packets or a hanging Damprid towel might be your best bet. Also, air movement will dissipate rh as well, so even if you can just move the air enough in the box without overdoing it on the buds themselves, that might shave off a few % as well.
