I don't know. My Lasiodorides striatus molted just fine without any excess humidity added to the vivarium. And she was fine while her exoskeleton hardened to. Within 12 hours after being in a molt position she was her little pisspot, anti-social self. Of course I think the key is that while in pre-molt she sucked in alot of water.
My camera needs a battery, plus I need a better lens. I have a Kodak digital. I wish a caught it on pics!
for many t's (aphonopelmas, brachypelmas, grammostolas, to name a few spp.) I feel as long as they have a water dish and are able to hydrate themselves as needed than the lack of humidity is not worth worrying or stressing over EXCEPT for lings and smallish juvs IMHO. I am of the opinion that adding water either by misting or wetting the substrate after the molt has started will only stress the tarantula. I keep the above spp. on bone dry coconut noir (forest bed) with a water dish available at all times and never or extremely rarely have had any molt problems. other more humidity sensitive t's are another subject.....
she is an adult female I got @ the Vivarium in Berkeley many years ago, she molts about once a year or so.
