cloning has nothing to do with yeild, the reson for cloning is to have a uniform constant supply of female plants.strain,light,food,and heat, are the four major factors in your yield, get youself a couple of clone domes for cloning , u can never have eneough colnes, use extra clones for tring new methods of growing thats the fun partso if your gonna do a 12 plant grow and aim for a few lbs cloning isnt going to give you the higher faster yield? just gonna give ya a jump start on veg time?
