Hi,
I've received the best results combining a few methods together. Here are the training methods I use and that you can use to maximise yield.
-Topping
-LST (low stress training)
-Defoliating
-Super Cropping
-Scrog (I have a good example of this on my 'Royal gorilla' Diary, can have a look and see what you think) Harvest was super heavy, with around 4-5 oz per plant dry.
Hope this give you a better idea.
