Hi Nick,
I am no vanda expert but this is my understanding:
Vase culture- no media
Pot/ basket culture- Fill in air pockets with growing media.
This link may help you for vase culture:

I would suggest you soak the roots in plain water (I use rain water) to make them pliable. Don't fertilize until you see new growth.
It is difficult to set a bare root vanda with no basket in a glass vase.
Alternatively, you can use clear plastic pots and tie the vanda up with wire.
I had the same problem when I received my vandas last week.
I ended up putting two vandas (with baskets) in vases, and one (originally in bark, but fell out of its pot in the post) in a basket with spagnum moss mixed with diatomite.
What is your growing condition?
Maybe some other members from your region can also assist?
