Well, not that I'm an expert in any way, but through reading all the responses here, I have to jump in and advocate for S/H. I am new to orchids as well, and am in way over my head, but, due to a member here who is all about S/H, things are so much better, cleaner, and healthier.
I have all my orchids in S/H now. I too had a phal that was given to me, full of rotten roots, and had to literally cut all of them away, leaving only one small root. I use clear glass vases or jars, (what ever is attractive to me) and I drill a 1/4" hole about half way up the container. This serves to hold nutrient rich water (always us RO water) and it also aids in the required humidity levels. I learned all this from "First Rays". Anyway, I got the hydroton pellets (this instead of any kind of bark which is not only messy, but will rot, and can also be a nice cozy environment for bugs) and put the phal into that, using a rooting hormone to boost the growth of new roots. I have to say, this phal is happy.
I can see the bright green root tips inside the glass, and it's putting out air roots, and new leaves. I grow mine indoors, under natural light LED track lighting, in my living room. Hope this wasn't too much. Probably was, but I hope it helps.:good luck:
