Should I repot my seemingly happy orchid?
 

I inherited a white phalaenopsis orchid from someone at work who believed it to be "dead". I know better, so I took it home. All blooms had wilted and fell, so I clipped the spike back just a bit.
It's been a week since I've had it at home and I noticed new root growth as well as a new arm growing from the spike. All seems well, however I'm concerned with the potting media and pot. Pot is solid glass, no drainage/air flow. I'm almost certain there is that green stuff inside the pot that florists stick cut flowers in for an arrangement. Around the roots is a mossy type of stuff. This all prevents me from seeing the roots.
I visited a respectable nursery today and inquired on repotting. I was advised to wait since the orchid seems to be flourishing.
I know orchids need airflow and drainage, though!! What to do...

REPOT!

You have already identified the problems with the pot and the medium. Putting the plant into good growing conditions will only help it continue its recovery.

REPOT! REPOT! REPOT!

You have active root growth. There will never be a better time.

It's already been said a few times, but REPOT

I agree, repot. Once it starts going downhill it might be impossible to save.

Repot for certain, but just because the current container doesn't have drainage doesn't mean it's not suitable for the plant. One of my old aquarium customers grew Phalaenopsis in regular glass vases for a couple years. They were potted in plain old pebbles of maybe 3/8"-1/2" size. The glass was clear and his watering regimen was very simple. When the roots turned white he filled the vase from his tap, which being from the same source as mine averages around 200 ppm tds. The plant soaked for a couple minutes and then he carefully poured all the water out. The roots were then a nice green color, and he just sat the vases on a suitable windowsill and ignored them until the roots had turned white. He then repeated the process. His plants thrived and bloomed regularly.
