no thechnique really....just like a landscaper would do a hedge...well like i said, i was using it to trim her down to size, the wame way you would trim any normal bush....say she was a 3 foot bush when i started...so i took about a foot off the top....then lollipopped the bottom to promote more growth up top...
then when the top would grow another 2 feet, i would chop about a foot off....and i would keep doing this to keep her height down, and eventually when she was too big, i chopped about 1.5 feet off the top and flowered her the next day....if i had of let her grow she would have been more bushy and produced more
