"Expensive" depends on your horizon.

Scenario 1: Buy bark & charcoal & perlite for each pot. Replace annually.

Scenario 2: But LECA once. As you move up to bigger pots, merely fill in
the extra space.

Yeah, that initial potting up is less expensive in scenario 1, but in short
order you will find that scenario 2 is far less expensive.

The hydro pellets are superior in almost everyway. Unfortunantly they are
relativly expensive. Something else that no one mentioned is that
volcanic rock is often high in flourine.

plentifull in Hwaii.
