so i am going to be getting the reptile basics sweater box rack, and i really want to move my bps on to unprinted newspaper since cypress mulch is getting so expensive. Question is how is the reptile basics rack at holding humidity with paper substrate? will the water bowl be enough to keep the correct humidity?
for people with RBI racks do you have to put holes in the tubs or is there enough air flow without holes?

thanks for the help
Tom
