do a search here on RIU about cloning and it cant get any easier. But yes usually from the lower branches taken from around the 2nd or 3rd row of branches after the plant has grown for usuallu 3 to 4 weeks.. Cut at a steep angle apply root stimulator then put into rockwool cloning Plugs with the slitz in the side and get a cheap cloneing dome from lowes. good luck mate
the reason why nobody responded is because that question is so basic you could go anywhere on this website to find that answer. people only answer questions worth responding to(and i question whether explaining that to you is even worth it)
