The best is to do both really, top it then when it gets pretty big tie it down , thats what I like to do anyway...If these are autos I wouldn't do any of training...If not it just depends how long you wanna veg and how big of a bush you want to grow..I like to keep tieing it down and topping for like 6 months untill the trunk is as thick as my arm lol..just for fun..I usually have atleast one giant bush I am crafting sitting around. You do need the right strain thou and really nobody can tell you if its the right plant for it cause they probably have a different pheno, your enviroment is different..there is so many variables...even then its not something you can really predict..however, if the plant likes to bush out already then its the best kind..
