phalaenopsis tetraspis with no roots

[Mistlebee15]

Thank you both, I will pot up later in some fine bark as suggested.

When I first got it I soaked in in some water for 5 minutes and only one of the roots turned green, so came to the conclusion that the rest were dead. I have just starting collecting other species, and was working on the same theory as I would do with my moth orchids. ?

Should I water and feed the same as I would normally until the plant becomes established?
