I recently bought 2 phal's and they came in the mossy kind of media....and i really dont like it..... i'm afraid that the roots will mold easily. also when i bought it, it was pretty moist because it came in a plastic container inside of a terra cotta pot. should i remove the plant from the plastic pot? it does have holes on the bottom to drain. also since i don't really like the moss, can i use other potting mediums? they both are in bloom at the moment, so should i wait to re pot them?
