At first that sounds like a rather stupid question but there is some reasoning behind it.
Lots of times when there is a "Help, my T is stuck in a molt" thread someone suggests taking the cage into the bathroom while a hot shower is happening to increase the humidity & help the spider molt. This is always met by many others as saying this is useless becuase a T can't absorb moisture from the air like that due to the waxy coating on the exoskeleton (juvie & adult, of course, sling haven't developed this coating yet). The same thing happens when someone suggests putting the T in an ICU...others mention that ICU's are useless since the water has to be ingested, not absorbed.
Given that...does that statement of "Species X needs to be kept slightly moister than Species Y" make any sense? Sure, in the wild the amount of moisture will determine what food is available or what predators will be around or how much standing water will be available to drink. But in captivity food sources are provided by us completely independent of environmental factors, we remove all chance of predators, & we provide water bowls or drops on the web for drinking.
If a T can't absorb outside moisture, then beyond having slightly damper substrate to make burrowing eaiser for those species that do burrow...is there really a benefit to having a damper enclosure? You can certainly have too much moisture in enclosure (get mold, rot, muddy sub, whatever) but can an enclosure really be too dry?
