I have one of the hybrids you have, purchased over the summer and is doing well. I think now it's known as Clowesia Rebecca Northen from what I was told.
maybe this might help:
Sunset Valley Orchids - Grower and hybridizer of quality orchids, Vista CA
congratulations on your new seedlings, I'm sure you'll grow them well.
By the way, I'm originally from Bandung and currently living in Maryland.
I'll be going back home for visit to Bandung sometime next year, maybe you can show me around some of the greenhouses or orchid nurseries in Jakarta.
