I clone and after 5 days uncover and place under the plants just enough light to penetrate. After another week I place them as normal and all goes well, 98% success rate lol. But have found that cloning takes way to long for me, But regeneration is the way some people don't, but from personal experience I cut to a foot with some small growth still on it, and right about 1 month no more I had a 5 foot plant so, everybody has their own way.
