Ya i suppose if you take a long enough cut it will work, but i do the same as you, just cut the very top of it off, with very little growth on it, sometimes i get lucky and get the FIM technique...lol.
when i cloned my babies.....they were only like 2-3 inch tall and all of em rooted...wut u could do too is top the one you got growin, clone the top and turn it into ur mother,then take cuttings from ur momma when shes ready to get clipped.......
