I repot my Phaleanopsis even while in bloom....you can use the same pot but change the media if you are not comfortable with moss....
that is a NOID....its really hard to identify a white hybrid because we can be decieved by its form, unless you can trace the seller on the chain of store that you bought it from and ask for the name of the whole bunch of plants that was delivered on that specific date

Thank you for your reassurance on the repotting the phal during bloom. I just don't want to repeat what i did to my first orchid when the sphagnum moss just constricted the roots with water logged moss.

I have mine in a plastic pot that came with the phal(s). Is that OK to use? It has drainage and it is clear.

Yes the plastic pot is fine. It is not uncommon for healthy Phal roots to be yellow because they have not had any light on them. The become their "normal" color when exposed to sun light.

The next time you purchase a Phal in packed sphag, wait until the exposed roots turn white, then water around the edge of the pot. Some moisture will wick into the middle but it won't be soppy wet.

Thank you Brooke. :waving
When you mean white, do you mean silvery white? On one of my orchids, the roots closest to the monopodial 'bulb' are becoming winkled. The other parts of the roots inside the pot are still semi moist.

The roots inside the pot will start to turn white when approaching a dry state.

Yup... silvery white...
Perfect time to water again

I see some white, but mushy looking ones. Are those decomposing already?

Roots that don't have access to light range from yellow to pure white.
They look mushy to me but are actually healthy..
Normally unhealthy mushy roots steer brown or black.

Thank you for the clarification. I may put the orchid where it has more indirect light for the roots too.
