how are you measuring the humidity? 85% is too high for a bp. I only reccomend humidity holding substrates (ecoearth/coco husk) for bps in glass tanks since aquariums with screen tops don't hold humidity well. If the snake is in a cage like the one in the pic, then aspen is probably needed because those cages hold humidity better than aquariums. bps should have ~50% humidity... bumped up to around 70% when shedding.... Aspen is a good substrate, its not toxic like cedar and pine and can pass through a snakes system without much trouble. 

If you're going to keep the ecoearth in the vision type cage, you can use a lamp but only as supplemental heat as your silly snake will probably hide somewhere while it digests food = you need belly heat. If you're set on moving your snake to a screen top aquarium, do not use a lamp unless you have a way to keep the humidity up (lamps suck out humidity). When you have no humidity => stuck sheds => missing scales/tail/deformities etc...

Sorry my response is all over the place :P

Also, try to find a lock for the vision type cage. IMO, that cage is better suited for a bp than an aquarium and once your bp fully settles in, you're hardly ever going to see the snake (except for when it's hungry) since they're nocturnal pet rocks who live in termite mounds... a few more clear walls won't really help you observe more than what you're already seeing lol...

Elexus: Eco-earth is being used simply because the cutie was sprung on me and it was what I had left over at the time. I have a hygrometer somewhat like such to measure: 

When I had my corn, I started out using a lamp before I realized he didn't really need it, and I didn't have too much trouble with humidity and coco-husk. I would simply lay a hand towel or some of that eco carpet over the screen. The other reason I was thinking of moving to an aquarium was to provide some climbing opportunities as the place it came from said it seemed to enjoy doing such.

Sorry for the double post as well, but I was also worried that hte Eco-earth was too powdery. My boyfriend uses it for his female Retic, and she seems to always have a dirty nose from snuffling around.

Use aspen.

I know Lowe's carries the sliding glass door locks, look where they have the mailbox locks and house numbers in Hardware.  I also like to use a mix of EcoEarth and aspen in my 20L tank. It has a UTH and I cover most of the screen top with glass panes that I can slide to adjust humidity and air flow.  Aside from the basic husbandry differences that the others mentioned and being nocturnal, they're sweet pets, I handle mine in the early morning or late evening.  Good luck with your baby!
