"My friend has told me
they're slow and often recalcitrant even in sterile culture."

I remember reading many years ago that you need to add charcoal to
paphiopedilum and other terrestrial orchid agar medium because the roots
will only differentiate toward darkness.  Give it a try.
These days most people don't use flasks, but deli containers with saran
wrap (which comes off the roll sterile).  Make a little laminar flow hood
with a sweater box, a fan and a 3M filtrete filter.
Have fun.
