It seems I'm getting stones now, only thing I did different this time is I used LC transferred to grain whereas my previous grow was from spore solution straight to grain.

I'm leaving one jar to keep developing the stones, the other two I have had small ones going but I shook the jars to get them fully colonized to spawn to bulk, maybe they will form in the sub better this time since there was some already started.

I will post a pic of the stones that have started soon, mine are tampanensis as well.
