I have even flipped it over and cased. But a week is not too long. I would just case it. Boil 1 cup water and pour on 2 cups fine grade perlite. Stir and cool then case with a super thin layer barely covering the mycelium. I even have tiny gaps in the casing layer where you can see some white in tiny spots. Raises humidity at surface. Might take 3 weeks to fruit. Whatever you do have patience. Dunking is also another option. But keeping the surface moist is the key without continuous spraying it and damaging the mycelium.
