I'd seriously try and bring a crop or two to harvest before learning 'advanced' techniques. You can easily stress the lady if you start removing branches and leaves, (a common cause of hermaphrodism) especially if the plant isn't stress-free to begin with.

Kinda hard to agree with a yield-increasing technique, when the technique is to remove yield. Regardless...chasing the possibility of an additional gram or two is not worth the possibility of hermaphrodism, unless you know what you are looking for and what to do if the nanners appear.

The best yield-increasing technique I've ever come across, is to let them be till harvest. (and a weekly teaspoon of molasses per gallon of water added their nutrients)
