Dendrobium cochliodes is growing

I was very skeptical about these dendro cochliodes seedlings since my previous attempt with den. antennatum seedling of the same size ended very sad.
This time instead of net pot with sphagnum, I potted them into clay pots with chc.

Not sure if these seedlings are stronger, or chc is better for them or it is just a matter of occasional luck, but all of them are still alive, growing new roots and one of them even started something that looks like a new cane to me:



I am still keeping my fingers crossed, but these little activity signs are pretty encouraging.
