5 gallon fabric pots. I just top and bend them young. Then train daily for couple weeks till stretch stops. As long as the plant grows healthily and cooperates a little with stretching, daily maintenance can get you any shape you want. I always mess up by being too hasty and break branches. That screws up training sometimes cos that part can't be touched. Otherwise, its just a guy with too much time on his hands.your training is insane what size pots are they in pal your style intrigues me
