I think what's being discussed here is simply cutting, or pinching off, the main growing stem, just as you might with other kinds of plants.

LST ("Low stress training") is something you should research; you'll get tired of cutting off all your growing tips, and the plant might, too.

I like that green-plastic coated wire--like the twist-tie from a loaf of bread, except on a long spool--$2-3 at Home Depot. Punch some holes around the lip of the pot to secure it, and start tying down the tallest shoots. :thumbsup:
