I was thinking more for my kings. I'm still trying to decide what substrate to put them on once they get bigger. They like to burrow so I'm on that neverending quest to find a substrate that permits burrowing and you can feed on. They don't need high humidity so I wouldn't be misting or wetting it at all. Of course I was afraid it would be difficult to spot clean - especially since their 'present's are small right now.
