I need my bums inputs on a question:

If my tupperdore is sitting at 65% solid without humidity packs/accessories inside - is there any concern with leaving the tupperdore without humidity pack/accessories until the RH starts to drop below my desired (62-65) level?

To add, the humidor has had around 50 sticks or so that sat in 70% for 9-10 months. I'm thinking it's the residual hydration, plus some residing in a bit of cedar I have inside, that's keeping it stready without help.
