Sounds about right to me, but I have never found my orchids ever actually
need repotting into bigger pots - they /like/ having their roots cuddled!

And about once a month, submerge the whole thing for 5-20 mins in warm
water. (ok, I don't get the flowers wet, but I put all the leaves, roots,
pot, bark chips, etc in the bath for a while) Then drain and don't water
again for, well, about a month. :-)
