Cattasetum in S/H

[dougbraz]

I was getting ready to repot my cattasetum fimbriatum into a teak basket (filled with sphagnum) so as to let the flowers eventually hang down - the pseudobulbs are due to start growing out again in about a month's time.
However, I was recommended to try a different method which would consist of a s/h method using a plastic coke bottle (2liter size) with some holes about two inches up from the bottom, filled three quarters with Leca and then topped off with regular pine chips, coconut and charcoal. A S/H with a variation, as it were.
Does this sound feasible - or unnecessary to add the potting mix?
Thanks for any pointers.
