Question, RH = relative humidity correct? relative to what?
It is a %. What is it a % of?
Failing to understand a basic husbandry requirement leads to issues. RH is just a number and meaningless with out the other end of the equation. To answer if you even have enough humidity or too much depends of what you are taking a % of. You need to know what the saturation point of the air is, to know that you must know the ambient air temps.
High humidity is not often an issue (unless it is actually wet inside) and there is a decent air flow. If the air flow is poor it is a huge issue.
