Thanks!
Most people would probably take cuttings from the plant(s) they like. These cuttings are clones that you can root and veg for about a month. After you harvest the current crop, you'd just move the now bushy clones into flowering stage.
And repeat.
Also there is a technique called re-vegging. This is where you harvest your plant and then put it back under veg lighting and veg fertilizer.
This is a little process can be considerably slower then the cloning method.
