The clones we have taken are shooting up so fast and turning into nice bushy plants, which why i asked the Q, would it reduce yield to clone from a clone etc etc.. I aint got a very good eye for catching males/fems early on, cant really tell until i see hairs or bloody big balls !! By that time the males are frikking huge( biggest was a hash plant at 3'4") and a pain to try and get rid off.
