Housing for young common boa

[Saml8]

I know a tub is going to be the recommendation however I'm hoping someone can give me advice on keeping boa's in glass (at least until he's up in size). I have a exo terra 36x18x18 and I would like to put my newly acquired 9mos old bci in. I live in Colorado where our humidity is low so I know keeping humidity up is going to be a problem. Any suggestions on combating this? This exo terra has a screen lid so I'm guessing I need to figure out a way to seal this off. After that, are there substrates that would help more than others?
When he gets bigger I plan on getting a large pvc enclosure which I'm guessing will help with the humidity problem.

Thank you so much for taking the time!

The exo terra should work fine for a youngster. Unless fed heavily, this should work for a while...and generally boas shouldn’t be fed heavily, slow growth is healthier for them. There are a few substrates that help with humidity. I’m using Reptile Prime in some humid hides, which seems to help in my situation for the winter months. In another month or two, humidity won’t be as much of a problem for me. This product, as well as other coco fiber products, work well for humidity retention. As for the screen lid, yes, you can cover or partially cover the top to help with heat and humidity retention. How do you plan to heat the enclosure and how will that heat be regulated?

Forgot to mention, yes, you will find that with the plastic or pvc enclosures it is easier to maintain heat and humidity.

Second thought, to help the glass retain heat, you can wrap three sides with rigid insulation to retain more heat.

Our Dumeril's is still in an ExoTerra and she's doing great. Substrate can help humidity - coco fibers or cypress mulch are generally recommended. I personally use Reptile Prime. I mist cages every day or two and will heavily mist once a week during spot cleaning. I've also heard others recommend laying a damp towel over one half of the screen to help with humidity.

For heating (which is also how I heat my corn snake enclosures): UTH under tank on 1 side plugged into a thermostat. A CHE (also plugged into a thermostat) on the other side of the tank keeping the ambient temperature up. Our house gets pretty cool at night.
Definitely open to other suggestions?
-- also, can I get a recommendation on what my temperatures should be for the warm side and the cool side?

Question about misting... when you heavily mist once a week are you misting the substrate or just the tank itself?
Misting enclosures is new to me. My corn snakes do not require high humidity but I do supply them with a moist hide when I know they're going into shed. I keep them on Aspen bedding and keep this completely dry.

For my boa, I keep her ambient in the high 70’s to 80F with the hot side around 88F-90F using a rhp. I have this range of gradient because my girl is in a 8’ long enclosure, so she has several zones. That is harder to get in a smaller enclosure, but doable. I’d aim for 80F low end to 88-90F hot spot.
