One way to reduce height is to completely cut down the stalk to 3 feet or so once it's gained some decent height. I have a tall braz. that flowered at around 7 feet that I did that to. Sure it sets it back a bit, but not much. As long as the plant has at least 6+ leaves to grow out before flowering after cutting, your good. I think the bunch size will be larger than restricting its roots, but I could be wrong.
