yes you can its actully a method some growers use called monster cropping they will take a cut from a late flowering plant and put it back in veg it makes it much harder to root a cut like this and it will take along time to root but when it does it will be mutated. The mutation causes them to grow like crazy in each and every way. its pretty cool to see to be honest its just alot of hard work to actually pull it off. best of luck though also auto flowers cannot be cloned only photoperiod strains can do this.
