Terrarium

As far on my research,HL nepenthes can be grown in an old aquarium with only one easy and cheap thing.That's Ultrasonic fogger.
It's controls humidity, temperature and the nice fog which will create a natural look.
I'm planning on growing a Rajah in 3 feet aquarium but since the plant will get so big, i'm thinking of what should i do next if the plants grow bigger.
I know this is not a matter that you should be concern about now since Rajah grows very slow.

Any idea?
