Optimal humidity for P. cinereus?

I have been reading through the available literature on these guys, and the verdict appears to be that they enjoy high humidity. But what does this translate into on a humidity gauge? My terrarium is currently at 90 % humidity. Is that too high?

Your humidity level is OK. The only real risk, I see, with high humidty is bacteria and/or fungal growth. As long as they have a moist hide I don't really pay too much attention to the relative humidity of the tank.
