Sabud, A clone is a way us growers can avoid starting from seed over and over again.... It is a clipping from a marijuana plant that is then planted once again, and if done correctly will root and become an exaclt replica of the plant it was taken from. Im sure the link that has been given in this post will clear up all the details for you on how to execute and use this technique to your advantage..... good luck bro. Hope this gave you an answer or two?
