Hi Edwin, welcome to the OB! nice to see your white Phal is doing very, very nicely. Congratulations!
I too started with a white Phal (first 'chid) and I still have one. The newest hybrids have huge flowers and I always tell myself I must get one.... hasn't happened yet because I now invariably find myself buying orchids that you don't get at the local shop... But whites (of any kind) are my favourite colour blooms.
And yes your plant definitely looks like it is planted in bark.
