100% Aliflor?

[psyc1210]

I have been reading info regarding s/h....and I've been trying to find something else to help my dendrobium that I received this past summer, and I recently repotted it into a bark mix, because I discovered that it was in 100% sphag, and the roots were TERRIBLY rotten. I am actually worried that it won't make it. Even though the foliage looks lovely, and there are two new canes starting...still, the roots were so bad. So I wanted to repot into something that will not break down at all. And I thought about doing 100% aliflor, but not using a semi-hydro pot....just a regular bottom draining pot. Is this a good idea, and will I be needing to water it much more often than it needed to be when in bark mix...also, if this medium is appropriate, would it be good for my phals, cattleya, paphs, and my new miltonia?
