this is true and will help I've done it for my blood.. take a tub-a-ware container with a lid, about the same size as one of your hides. with the lid on cut a hole the size of the tight hide hole in one of the sides, put the spagum moss in and soak it with water, drain out the excess and place it where you have one of your tight hides. that should help.. I've also been told that having lamps help to pull the humidity out of the tanks.. good luck, cheers
