indoor growing in australia

[James_88]

im thinking about growing a plant in the wall of my bungallow for my own personal use. i live in victoria in australia and i was wondering what would be a good type to grow. i dont want anything very big, about 4ft would be ideal. the more potent the better. any suggestion would be great. i was also going to rig up a computer fan or similar that would blow the air out of a small hole so as it wouldnt smell, wold this work?
