I moistened my slings pill bottle yesterday (Done twice weekly) and today when I looked into it, there seems to be a bunch of white crystal looking things in small sections on top of the substrate (eco earth). They vary in size and appear in certain places not all over. I have seen this stuff quite a few times already and removed it. It does not look like mites as they do not move at all and it does not seem like mold because its not that cottony stuff and there is sufficient ventilation. I was just wondering if anyone else had seen this stuff before or knew what it is?
