OK, if I read you right, you don't "quite" trust this growing method, at least not long-term. Oh well, I guess I will just keep mounting/hanging my Vanda plants unless someone has longer experience in growing orchids in semi-closed containers and can tell me what works longer-term.
Thanks, Gigi. And yes, those roots do look very healthy. Was the orchid bought in this glass vase? If so, I assume it is simply a gimmick, the same as those Phal. bought in the big-box stores, in cheap, non-draining, plastic vases.
