Best bark Size/Grade for Paphs

[RosieC]

So, when I got my first Paph last year it came in a very large grade of bark (much bigger than my Phals are in).

When I repotted I used a large grade mix because I assumed that was what it needed (as that is what it came in).

But now I have read several times that Paphs need a fine grade bark mix and so I'm usure. It seems to be doing OK in the large grade stuff. I've not had massive amounts of growth this year, but there has been some.

Do ALL Paphs need/prefer fine grade, or is it possible some prefer large grade? The Paph I got last year is a complex bulldog type of Paph and the roots are much thicker than something like a Den (which I know needs fine grade for it's fine roots). They are brown and furry roots and are perhaps a tad thinner than a Phal's roots, but not by much.

I bought a new Maudiae Paph yesterday and that is in much finer medium. I haven't looked at it's roots yet so I don't know how they compare.

Can anyone advise me on whether my Bulldog type Paph would be better off in a finer mix
