moss or bark for phal?

[mayres]

Phals can easily successfully be repotted at any time - including during full bloom. My suggestion is that you repot any/all phals as soon as you get them into the media of your choice - that you are comfortable and have learned works with your cultural habits/technique. I've gotten way too many phals (even from reputedly good commercial growers) with less than desired roots - usually planted in sphag. If you do it immediately upon acquisition there should be no doubt going forward that whatever issues develop YOU had a hand in - both good and bad. Amazingly that crammed into the pot sphag media DOES work for some growers, but for the majority of us home growers doesn't seem to be the best option. Have you considered other options besides bark or sphag? I pot all my phals in a coir mix and have been super happy with it (approx. 70% coir, 25% perlite, 5% charcoal). Lots of options will work - you just need to find the best option for your conditions......Good luck...
