I always moisten mine to a point where you can squeeze it and it packs together and no moisture comes out, but it crumbles with little effort.

Good luck with it.
With perlite I like to use a piece of egg crate cut to the size of the tub.. Lay the piece on top of the moistened perlite, and put your eggs on the piece of egg crate... Your eggs get their humidity, and never touch the medium... You dont even have to squeeze out water...
