You'd have to breed your plants and get seeds, cloning auto-flowering doesn't work. So I understand, the reason cloning does not work for autoflowering plants (in your case, Lowryder) is because the cutting wouldn't really have a change to vegetate, it would try to start flowering pretty shortly after it was in a growing medium.
I'm not saying that someone can't come up with a way to do this.. but to the best of what I know (and what I can find), no one has been sucessful yet.
