I leave mine under the dome for 2 weeks. Some strains root faster. Out of the package, they should feel moist, like a loaf of fresh bread, or a new cellulose sponge. For comparison, take a wet cellulose (the good kind, like the yellow 3M ones, not foam) kitchen sponge and squeeze all the water out of it until you can't get any more. It's still wet, but a good comparison to a RR with the right moisture content.
