Dendrobium bellatulum blooming troubles

[Rothrock42]

I've had this Den. bellatulum for a bit over a year. When I got it, the previous owner had given it a VERY dry rest period. I think perhaps a bit too much. I moved it to oak bark and it has taken off and even sent out some bloom spikes.

The first one, about two months ago, never opened and it got that wrinkly blasted look. Then this one started.



It too never opened, but it has started swelling at the base. I'm thinking that might actually be a selfed seedpod forming?

I have stopped daily waterings and just give it heavy mistings once or twice a day. Humidity is about 50 to 60%. Since I started the "dry" period I've seen three more buds starting.

Any tips on helping this next round of buds actually open?
