As you can see, it depends on a lot of factors. I have 2 in a bark/ sphag mix.
Of all medias ,recycled or not, used/ experimented with to save money 'aquarium filter sponge' has been most succesful in direct relation to my grow situ. Apart from black the only alternative choices in terms of more compact or more open are blue and red so i tend to make friends with people who keep fish and buy them a cake about once a year.
Packaging like poly beads/ stryofoam is useful in confined areas like pots or holes in branches to open up space for air flow. I recommended it/ shared idea with a member here for pot phal culture. Ofcourse this is only applicable to moist, high humidity grow areas as water/moisture supply would be inadequate. My phrag bessae grows in container with sponge chunks and rock wool and with sphag for acidity need. It hates bark, med and lge grade?.
