I personally think anything below 50% is too low. I prefer my normal humidity to be between 60-70% and in shed to be more. I have never had an RI ever. If your air is stagnant and enclosure is dirty, yes it could promote bacteria growth. But I have good air circulation and clean my enclosures every time they are soiled.
If you look at a BP's natural range, the humidity in Africa is pretty high.
I read online pass 75 can cause possible RI's or promote bacterial growth. Is that false?
That is bit misleading. The average humidity in the parts of Africa that BP's come from ranges between 48%-95% with the average being between 77%-85%
The problem isn't the humidity, its condensation and low airflow. As long as you have adequate airflow and no condensation forming in the cage you shouldn't have a problem.
I keep my cages at 60%-70% humidity normally without any issues.
