Personally, I don't mist Budo. An eyedropper works much better for getting the fluid in their mouths, and in terms of
hydration, misting really can't replace a
bath. Beardies absorb most water through their vents. Therefore, misting should not replace soaking. Misting also chills beardies, whereas baths are easier to keep warm. Also, it's not good for them to remain wet for an extended period of time; thus, toweling after baths and basking.
Anyways, many people mist their beardies, it is not by any means a bad thing to do, I just personally prefer not to, for reasons specified above.
