Got a new phal for a steal

[Shinnok]

I was in town yesterday, I was on my way to get a drink and saw this Phal outside the store under the sun without shade.

I went in the store and ask if it's for sale and she said if i want it, I could buy it for 10 chf (it cost double or more usually here in switzerland) besides she doesn't have any patience to wait for it to bloom.

Well anyhow i bought it and clean it a bit today on it's leave cause of dust collecting. (can see on the picture) Here's the picture it down look like it's growing too tall with a lot of roots. Not sure if i should repot it.

Any advise???
