technically you could get a clone to root but it would carry on flowering at the same rate as the parent plant so you would end up with a smaller plant and a tiny plant trying to root and finish its flowering cycle at the same time. you cant keep a clone vegging as its an auto. making seeds is the only way. dont be afraid of it. so many people are shit scared of males but it easy to make a few seeds.
pick your best male and female and lock them away together just before the male spills his pollen. every day give the male a shack over the female. after several days bin the male and spray water on the female to kill the rest of the pollen, she can then go back in with the rest and you will get around 500 seeds from her so you wont need to pollinate again for a while
