From what I read, phal orchids like light to get to their roots. I am currently putting them in clear plastic slotted orchid pots, which I then place in slightly larger "cachepots." All of the cachpots I have are opaque ceramic, so I am thinking about purchasing clear glass vases to use as cachpots. Does anyone do that? Is it a good idea? It seems like it would be if phals like their roots getting light. :-)
