Cattleya repotting - compacting media

[guccisimo85]

I just reported these two cattleyas. I read online that the media should be compacted enough that you can lift it by its stalk and it shouldn’t come out of the pot. I have really compacted the media quite well but they are still a little wobbly when I lift them. The smaller one would come out if I held it too long.

Wondering if it’s because there is not enough small bark in my media? I mixed medium and small bark, sponge rock, hydroton and charcoal. Or maybe they should be potted deeper?

Any tips/suggestions are much appreciated!

Thanks!
