It all depends on what cigars you have, and how often you check your humidity level in your 'dor. Right now, my small 'dor only has a few Punch Rare Corojos in it, and since they're all the same, i took the cellos off, in order for the aromatics of the spanish cedar to do its thing. However, if you have some super mild's and a couple full, strong cigars, i would keep the cellos on, however, i'd open the ends, so that the cigars could breath, otherwise, they'd just take up the rest of the humidity in the plastic, and dry out, even inside your 'dor. So i say, if you have all the same cigars, (or similar cigars that you don't mind "merrying") go ahead, and take those cello's off, otherwise, just open the ends, and let them breathe a bit.
