Where am I likely to find Turface(Calcined clay) for growing media use

[st0ric]

So I am looking to put together one of these PPK systems popular on icmag at the moment and am looking to avoid the issues inherent in coco(bugs mainly) so is there anything out there that will work like what the yanks use known as Turface which is just calcined clay in the right sizing to be good for a growing media as far as the reading I have done has told me. Only thing I can think of that is similar is clay kitty litter but fuck that shit is 80% dust.

Have no idea what a ppk system is but is this the same clay

seems to be made in a similar way & a very fine powder

Its basically a recirculating flood and drain system and I think it needs to be about perlite and slightly larger sized not a powder as that blocks the tailpiece of the top bucket
