This thing grew quite a bit of green mold between the wood and the sides of the container before I ever put anything in it. This makes me wonder why sometimes I have rotted logs that never seem to grow mold no matter what, and other times I've finished sterilizing them and had them covered in mold the next day. Also, most of them in the wild don't have any mold on them at all. I have ideas as to why, but I decided to just try a little experiment to see how different conditions affect mold growth on rotted wood and to what degree. Even though some things seem obvious, some times I'm surprised.
I cut a rotted log into pieces and put them all in different combinations of conditions--aerobic, anaerobic (for the most part), cold, hot, sterilized, not sterilized, with springtails, and without springtails.
