Hi Iperialis,
The parents of your P. Cordova 'Roc' are:
P. Zuma Garnet X P. Golden Buddha
(these might be reversed)
Since Zuma's plants are usually small I would venture a guess that your plant would be of medium size.
I don't think it would require any special care.
If you would like more information I suggest you write to Mr. Peter Lin at:
Big Leaf Orchids - online phalaenopsis store
He has/had this plant and could probably tell you more about it. He's a great guy and wouldn't mind hearing from you. While you at his site, take a look around, there are some wonderful phals there!
Glad to hear you are into phals. I've got about 80 now but don't dare to really take a count!
Hope this is of some help.
AL
