Hi ken.. Firstly that is not a phal. its a dendrobium hybrid. if the flowers are fairly round, then it is bred from the white from of the Cooktown orchid, dendrobium phalaenopsis or dendrobium bigibbum. The roots look ok, so it should grow nicely. avoid covering the old pseudobulbs with LFS. if kept too wet, they will rot. Lighting is as for droseras or neps. True phalaenopsis take less light, somewhat like amps. You could consider repotting in a larger pot too. choose a pot that is just 1 or 2 inches larger than the rootball. Use charcoal, sphag is too wet for most dends. Good luck..
