Paph vietnamense--should I give it a try?

[Claire25]

Hi all,

I was wondering if anyone out there with experience in growing Paph. vietnamense would give me his or her two cents with regard to growing this orchid. I do well with Maudiae-type Paphs, but have limited experience with parvis like vietnamense. I grow indoors on a windowsill in the winter, where my Paphs get some filtered morning sun. It's pretty dry in here right now (central heating) and I don't currently have a humidifier in the room where they grow. In the summer they receive shade and copious watering (and humidity) on my back deck here in Maryland.

My specific questions are: would a bark mix with some dolomitic limestone added to it be appropriate for this plant, or could I get away with potting it in moss, as I have done successfully with most of my Paphs? (It'll be a seedling; I'm a little concerned about it drying out too quickly in the winter if it's in bark.) Also, does vietnamense require different lighting from other Paphs--specifically, can it handle any direct sunlight? And finally, how slowly does vietnamense grow? (I had a micranthum once that seemed to stay seedling size for years...would vietnamense be similar?)

Any other information on this beautiful plant would be greatly appreciated. Thanks so much!
