Cheap alternatives to "cigar" beads?

[markem]

Someone will possibly chime in with the brand, but there is one kitty litter that has roughly the same properties as beads. That is, it gives up moisture below about 65% RH and absorbs above that. Can't recall if it was here or at another site that the posting was made, but it was made within the last 6 or so months.

I've always used Heartfelt beads. Scott's beads have the same high respect as the one's from Heartfelt. I have 8 lbs of the heartfelt in 4 large storage units (2 vinos, 2 100 qt coolers) and one 1 oz tube in my 150 count Savoy humidor (new addition and the difference is amazing).

The funny thing is that I've always considered beads to be a cheap and safe alternative to other humidification devices, but everyone has their threshold, especially in a down economy.

It would be cool if the litter info gets posted and you are able to run some tests with it. For "humidify and forget" however, beads are my personal choice.
