I more so associate scale rot with wet/damp subtrate more so then humidity, but high/low/fluctuating humidity could also cause concern for a RI to pop up. Not by any means saying that it WILL but more so that it MIGHT. Just my 2 cents on that.
Okay that's good enough for me. That was my main concern. I guess I know what I'm doing this weekend. It'll be nice from a convenience stand point anyway.
