Clone is just a fancy word for starting from a cutting with certain conditions. In this case, mine, all four are sister(?) clones since they all came from the same motherplant. The mother was allowed to go to fruition so we can't clone this particular plant again. People try to clone from a plant if they find a good one since going to fruition means plant death. Remember the discussion of the 24hr/day light to one plant that is never left to seed? That would be the mother plant, clones are the children taken by cuttings - you know that genetically they are the same except for environmental growing changes.
