I know it's probably based with English growers in mind, but the Pleione website does say you can keep bulbs in the fridge over winter if the natural temps aren't cold enough: The Pleione Website
For Pleione formosana, I may not need to put it in a fridge during dormancy. If that temperature guide for Easy Orchids is correct, then I'd say, it can stay right where it is and it'll go dormant all on it's own.
When the new growth starts to grow it will be clearer just what is going to happen. That picture looks like the plant is still in a dormant state. I am guessing that the pseudobulb is large enough to produce a flower.
Congrats on the new baby. I recently got one of these as well, three bulbs with starter leads, and have it outside to benefit from our cold nights. Only thing I worry about now is that it'll get rained on - or misted by the fog!
Looking forward to seeing what happens with yours.
Very nice. Congrats on your new bulb. I got 4 bulbs and one bloomed early (my landlord watered it by mistake in January). But early or not, it exciting to see it open up more and more each day.
The top layer is mostly wood chips and perlite, with a little potting soil. This top layer is not all that thick, it only covers the dead roots and a little bit of the lower portion of the bulb.
