Time To Repot???

[yager]

Newbie with some plant experience, just not with orchids. This phalenopsis was in bloom when I purchased it. The flowers fell so I cut the stock off and put it under artificial light (sunleaves pioneer VI 6x54w) about one foot below lights. Watered with distilled water and fish emulsion mixture. Within 2 weeks new leaves started and the root grew like crazy. It is now pushing its second new leaf and as you can see the roots are trying to get out. Should I repot now or will I get a second bloom this year w/out repotting? The lights are on a timer for 12/12. I believe this is a Phalenopsis, it had the big white flowers you see in grocery stores and home depot. Any advice will be awsome.
