White patch is complete again, sort of

I have moved the last seedling into 6" container today, #111. I will now have to decide which one is COMPLETELY dead before moving any more.

I have used lightest soil to date with #111, with plenty of perlite and  small river rock. here is a view of the top two inches of the container before I filled it with more cactus soil and perlite:

I also placed it even higher than previous samples in the container to avoid the trunk being exposed to water:

The brown patch looks extremely healthy with vast majority of the seedlings liking careful water management:
