Great photos John! I have 2 lithops in the process of dying, I don't have any ideas of what to do, just watching them slowly continue to dislike whatever conditions I create for them! And here in Seattle it is still a bit chilly for them to be out all night
(so they're indoors under growlights)
I have bronco also and love it! Its a newish one for me and it is so pretty!
Cheers
