This is my largest bellatulum so far. This one grew quite fast. I believe that the plants were deflasked in October of 2004.
I grow them on the dry side by putting them in a chc mix in small pots. This one is in bloom in a 2 1/4 inch pot. Other bellatulums that have become multigrowths for me have tended to decline when I potted them into the larger, deeper pots I use for most of my Paphs. Next time I repot a larger Brachy, I'll use a shallower pot or a more open mix, or both.
I think the key for some of the Brachy's is to never let the mix get too soggy. A big plant in a 2 1/4 inch pot easily sucks up the available moisture. Over potting them makes them go down hill fast, at least for me
the flowers of your bellatulums are excellent and all three plants are well cultivated - congratulations, well done!!
Unfortunately my P. bellatulum didn't flower although it had two sheats this winter but both withered. I think I kept the potting medium slightly too moist during the 'resting' months Nov./Dec. therefore I will keep the plants cooler and drier next winter. I hope this helps.

Surprisingly, the bellatulums from this flask have been very easy growers compared to others that I have. Perhaps it is a result of several generations being bred "in captivity" or perhaps my culture is slightly different. On this batch of bellatulums I am intentionally using smaller pots than I normally would.
You are right about the moisture, GuRu. These plants dry out more quickly than my other Paphs. Best of luck with your bellatulum, this year.
