I top and lollipop most of my autos… If they have good conditions and are growing well, they will generally keep cruising right along and can have very nice yields as a result. I’ve also been able to clone autos and get nice batches of seeds from the clones.
Also, autos don’t work as if they have a timer. If they did, clones would flower at the same time and rate as moms, and they don’t. A variety of factors will influence what they do and how they grow. Many will even stack buds and reveg fur months after typical grow times if left to linger in favorable conditions. Torture them and some jump into flower, others will stunt…
