I'm growin a couple "bonzai marijuanas" in half liter containers (split milk cartoons) and they are doing great. Just for the fun of it to see how they turn out, doing quite well. But my mega-modified plants in their 5l containers are the greatest bushiest things i've ever had. Used all of the above mentioned techniques on them and they are really getting tons of colas and bud sites and very fat and busy yet small in height, keep havint to supercrop some though to keep them not too tall but that's just a plus.
