Humidity for ball pythons

I'm going to get a c snake rack system and I'm thinking of putting hertopia bedding but would that be too much humidity for a ball python? One last thing I know if a snake get stressed if it doesn't feel safe but if I keep it in a adult size tub straight off the bag but with 2 hides would it steel feel unsafe and get stressed ?

I user Herptopia in my pro-line cages and it is shipped very dry. It's not like some of the other coconut-husk products that are packed together tightly and need to be soaked in water to break apart. You can just dump it in to your tubs fresh out of the bag without wetting it down, so it shouldn't cause any extra humidity. As long as your tubs are holding the correct humidity without substrate, I don't imagine it would change by adding herptopia.
