Some people claim they can, but all the breeders say not.
The lifespan of an auto is too short and with flowering being un-stoppable, by the time roots develop, flowering would also be imminent, meaning very small clones that would flower by the time they have recovered and grown roots, so cloning would be a rather pointless exercise.
Never hurts to run an experiment or three though.
