advice sought on newly purchased Paphiopedilum tranlienianum

[BrucherT]

I picked up this little P. tranlienianum at Hausermann’s last month; it looked healthy and the price was right.

It’s out of quarantine now and I’m thinking about repotting. As you can see, it’s potted in straight sphagnum.

My inclination is to repot it into seeding bark mix with extra pumice, charcoal and limestone chips, or a Japanese Cymbidium kanuma/pumice mix but I wanted to gauge expert opinions here; have I missed something? Is growing P. tranlienianum in straight sphagnum, like, a thing? I do see one apparently nice root circling… please advise?

I have had my two-growth seedling for six months...The seedling bark mix (with extra sponge rocks, charcoals, and some chicken grits) works fine for me... I grow it I/W side by side with my helenae on the south-facing windowsill among some of my Brachys seedlings, kinda bright....small pot. I think both helenae and tranlienianum grow cooler and drier in their natural habitats in winter.
Crazy Tony posted a nice one not long ago, not sure if he gave out any culture tips...

Just by looking at your hand, your plant is so much bigger than my little seedling, nice buy!
