Robertsanswered grow question 3 years ago Do not top your auto... they don't have enough time , and it is too stressful. Simply LST her to improve light on inside of plant. If In soil do not go cutting. If you need more information on lst. I have a diary called Larry lemon auto. I did a daily picture from seed to smoke. Picture was taken after lst each day. It was grown in a hydro soil. and just lst and defoliation at times. She produced over a qp dry. I have a profile full of autos I lst with results. Best results with autos is grown in a hydroponic setting. Be it hydro soil, soiless, coco, or a dwc etc. They grow faster, and bigger. I still don't top. If I ever did it was a accident, and it broke off. So I avoid it. Would be my advice after growing a bunch of them over last few years. Good luck and happy growing.
