i can see your point but it only takes what around 9 weeks from seed for an auto flowering hybrid
so cloning would be a lengthy unneeded process. I would recommend flowering one of the plants and using the seeds just crack them in something like 3 week intervals and go wild
crop every 3 weeks or so and when you run low of seeds flower one of them and start again
cloning can take some time and by the time you did get it routed and growing the stage it will be at would probably be the same as if you did use seed
