Yeah, but you can just do pure topping instead ;) (otherwise I usually hear and do it myself, I use YouTube, it explains it so my nephew pp 4 just wanted to do it;) . It's usually said to take from the first branches and then 3 shoots up, so 6 in total, 3 on each side, and clip. Otherwise, check out my Hydro and my KANNABIA indica cream, they are topped in both ways ;) best regards from Ngreen
