I'm flabbergasted at this point. Couple days ago I removed well over half the oversoaked substrate and replaced it with bone dry chips (put the rest in another tote) and it's STILL too humid. Not quite outreading the hydrometers now but still 80's-90's in percentage. Bored a bunch of holes in the lid earlier to see if that helps but this is just crazy. Worst thing is even if it lowers to acceptable levels soon the addition of his water bowl is probably going to shoot it right back up again.

Well, at least if I ever get something like a Brazilian rainbow boa I know exactly what to do.
