That's been my experience with Phals. The plants I switched in spring with new root growth did beautifully, until winter. We let it get down to 60'F at night in the winter and my Phals really suffered for it. Phals that I've kept in bark and mounted do better, probably because they tend to be drier, so less evaporative cooling.

Here are a few photos showing the great Dendrobium roots.

I think that the important take-away from this discussion is that while pretty much any plant (orchids and otherwise) CAN be grown in semi-hydroponic culture, not all of them will necessarily do well for YOU, because of differences in growing conditions and ones own habits.
