Thanks for the quick replies! Sorry no pics of my vanda, as no camera cable , but here is link to nursery I got it from
Anco Orchidee | Unique Dutch Orchids
If you scroll across you'll see a number like mine- all in base of vase with the whole plant inside. Mine is not in bloom and has lots of new root growth, but that's the only difference.
I'm trying to get rid of the white residue at bottom of vase (water? Very weak food?) and water and finger marks inside the vase, so that light is maximised for the English autumn winter.
Thanks for your help, and sorry again not to be able to show you my actual plant.
