Phal in bloom since December 15

[PaphLover]

Bought a gorgeous phal in December with multiple branches of flowers that has been in constant bloom since then. It is now growing some new roots and another section of 5 blooms off of one of the top branches. Only a few flowers have died off since purchase.

I have repotted it in bark media from the hard-packed moss it came in without trauma.

Am less concerned now that new roots are growing, but does there come a point when one should worry about over-stressing the plant by having it in constant bloom? What is the longest period that phals can grow/keep blooms?
