Reduce the light and you will reduce your yield. LST and hst will amplify nothing , it will keep them shorter and will allow you to build a shape but will not reduce the way they are growing , a tall plant remains tall and a short plant remains short , you can manage the height and size but that's all.
From seed you have different type of shape , smell and colours due to the multiples phenotypes available, you make your selection to keep a clone and maybe creating a clone only strain ( I am calling it a clone only phenotype , a strain is not a cutting )
