Let humidity drop to 10-20% and only bump it to 50-60% when about to shed (success)

I'm sorry but I don't get the bashing on Brian, he's a really nice guy and takes wonderful care of his animals. I've known him for a long time (although we don't talk directly any longer now that the local bay area CA reptile people don't all hang out on KS). I don't agree with him that snakes *have* to have belly heat but it's one of those things - different things work for different people. I guess there's something going on I'm not aware of? I just felt is was uncalled for.
And yes we average 50%+ natural humidity here in the Bay Area.

back to the OP - When I lived in Las Vegas for a few years, I had horrible humidity issues and lost my two GTPs and a baby BRB because of it. Almost lost one of my ATBs. My other boas, ATBs and adult BRB were okay in the long run but it was a constant struggle. I ended up having to mist every other day as well as keep a fish tank in the snake room to keep humidity up (didn't have a humidifier but if I still lived there, I would have got one). I'd still get bad sheds from time to time.
So yes, they can handle it, especially somewhat hardier species, but I wouldn't recommend it and it may cause issues in the long run. Please be careful.

He is obviously a successful snake-keeper, no question. His educational videos, and his narrow-minded advice are poor quality in my humble opinion.
