Hmm, now I keep it in the house and with the lid off. When I dump it in, it is Very moist for month or longer. So, I try to plan ahead and keep the oldest and dryer Cypess in another tub, i.e., I rotate when the tub is halfway down.

In fact, I was going to go go to Loews today since you can see in the picture that the tub is half full. But I didn't have the time for that errand afterall.
