I just brought a Nic BC home (my first snake!) and I'm having some trouble with humidity. I'm using a digital Acurite for measurements and the temps are fine I think, 75 - 86 f with a 93 f hot spot. My humidity won't come down past 80%, sometimes getting to the mid 80s. However, I'd dried out the substrate (cypress mulch) almost entirely beforehand, so I don't see any condensation or feel dampness; everything is seemingly dry and clean. I'm not sure if the current humid weather here may be having an effect, as I'm in an air-conditioned condo - possibly a little?
Should I be concerned about these current conditions, is it necessary to drill more air holes? My main reasons for wanting to keep it as is are a) I don't have a drill and need to ask someone to do it for me (I'll need to figure out how to keep the snake contained for that time, and he's just moved in so I'll have to wait), b) I'm worried added air holes would drop my temps, and c) it gets very dry here in the winter, and I want this tub to be viable then, too.
I've found mixed information regarding how harmful high humidity may or may not be for BCIs - from "it can lead to RIs" to "there isn't a maximum as long as the enclosure's clean and not constantly wet/mouldy". Advice would be greatly appreciated!
