Lefty,
I only open that big 'ol thing of mine about twice a week and most times less. What I do is keep a 100 count desktop on my desk and put a variety of smokes in it that I think I will want to smoke. Most times I just pull out of that, only filling it again when needed or the opportunity arises to add water or something like that.
I am only adding water to the Moist-n-Aire (in the big humi) about once a month at most and my climate is always 35% to 55% rh.
Personally I think you may be better off lining the trunk with spanish cedar if you haven't already. After that, get yourself a desktop. The amount of beads seems about right.
