Should I repot this phal?

[rbarata]

99% of all barks sold for orchids is fir not pine bark because, unless it is a specific hard type pine and specifically treated as is Orchiata, pine breaks down faster.

Well, as I explained before, fir is not a common specie in my country and, as far as I know, it's hard to find (if it is sold anywhere). Pine is used here for many things (related with gardening and many other purposes) with good results.

I would not pay much attention to anyone demonstrating how to pot orchids who does not know the difference between the two.

This statement is somewhat extreme, just my oppinion. A good argument could be: if pine bark is more degradable, so people who use it have much more experience in repotting orchids.
