i have a sterilite box setup for my 4 month old BP, with 2 water bowls in it. A big one on the cold side, and another inside a cardboard hide on the warm side.
My problem was, the overall humidity in the cage was pretty low when i turned on the basking lamp in the mornings (25 - 30%). so i decided to spread a damp towel over the mesh top of my setup, to bump up the humidity.
the humidity's kinda OK now, between 55 -60%. My concern is that the towel might induce fungal growth in the setup, cos the towel starts smelling musty at the end of the day. so is it ok if i just wash the towel once every 2 days and use it ?? (worried about inducing RIs here)

Another question was : is it ok if the water bowl in the cardboard hide on the warm side is directly over the UTH? its on top of the aspen bedding of course, but i read somewhere that this may be a bad idea..
