what kind of orchid is this?

[Greenthumb.5]

Don't fertilize it because it can't take up anything if it has no roots. Keep it slightly moist and mist it once a while. If you use the spag and bag method, it can help the grammotophyllum. It can photosynthesize a little bit and take in minimal nutrients through the surface of its leaves and pseudobulb. So in terms, keep it warm and slightly moist until it decides to kick the bucket or save itself with a new growth.
