Hello ya'll! I have these green mossy looking things on the roots of both my vandas... yet they both seem like different kinds of green?!? The first three attachments are on the roots of my Vanda Ascocenda Jose Coronado... the lighter greyish green stuff... ??? And the last two attachments show the bright green stuff on the roots of my Vanda Blue Tahourdin.. Both are blooming right about now, but these moss looking things are bothering me?! What are they? And how do I get rid of it?? I plan to repot these vandas after they're done blooming so maybe it'll be a good chance for me to get rid of that green stuff on the roots? Should I be worried about our health since they both stay indoors in front of a humidifier? Thanks a bunch!
