So yeah. I have an ARS 7030 rack and the humidity in the tubs is 44% or so on average according to my accurite. Even with the water bowl on the warm side. I use newspaper as substrate.

I keep the rack in my room. Should I just buy a small humidifier? Switch substrates? Which I really don't want to do beacause newspaper is free and Aspen or cypress or coconut husk cost money).
