Their is no definite anwser to this question with each technique a big yeild can be had. It all comes down to Time, space, equipment, and how much effort you want to put into it. It also depends on if your growing indoors or outdoors. Out doors the best way to get alot of bud with out alot of effort is to tie it down you will usually see almost double the amount of bud if done correctly. If indoors tieing down and toping is still one of the best things to do (and the method i prefer). If space is a problem then Lst, Scrog, And pinching/cutting is a great way to get alot of bud. Again it all comes down to your opinon what works best for you and is space a problem. Since you want to grow it quick and hassle free and get alot of buds i would say just tie the sucker down and let the lower branches get massive peace out and happy smokin
