You'l just have to keep a close eye on watering because the plant will suck up a lot of water, might have to water everyday, Shouldn't have to worry about root rot if you don't keep it too wet.
You can grow a four foot plant that looks decent in a 2 litre soda pop bottle.
you can do it, just need extra care and a watchful eye. Sorry I can't find any examples to post right now.
