Really? well that's good news! I was wanting to top her to get 4 main shoots and the LST the 4 main shoots... I would like her to finish about 3ft tall. How much do you think she will grow after i start budding her out?
It depends...
What I like to do with stretchy types is to top and trim so that she has 4-6 branches, and then use LST and pinching to pull the branches out instead of up. Once the stretch stops (usually 3-4 weeks after flip for the Killing Fields) let the branch tips turn up. This will keep even the tallest sativa under control. Try not to stress her too much at one time if you can avoid it. Think of it as a scrog without the screen...
