Black humidity beads

Same thing happened to mine. I think its mold. I threw them out when this happened.
 
Never seen it happen, but it sounds like mold to me. Send viper a PM, he may not notice this thread. I'm sure he can help you out.
 
I had 1/2 lb, when I got a bigger wine-o-dor I needed another 1 lb. When I got them I noticed a huge difference in color. The new ones were pure white but my older ones (probably around 1 year) were brown. They are not black like some of you are mentioning. Think the brown is mold too? I mixed them with my new beads so I really hope it is not mold.

give em a sniff. You all know what mold smells like.

Were bags or tubes in direct contact with Spanish cedar? The beads will pick up the color and turn brown. Its harmless.
