@BigBill @tarev Since I wouldn't be able to use sphagnum moss for re-potting, would you advise me to use mixture of finer bark and coir pieces, or only smaller coir chunks?
I do not have experience with oncidiums, so I'd like to hear your advices.
As a side no,t I usually water my phals(their media consist of only bark/no coir) every 5-7 days during summer, if that helps in any way.
