Can you top autos

Yes, you can absolutely top autoflowers, and plenty of growers do it successfully. If you search through growdiaries, you’ll find 7k+ examples where autos have been topped and still produced great yields with big, dense buds. That said, it’s important to understand the risks. Unlike photoperiod plants, autos are on a fixed timeline—you don’t get to extend veg time to let them recover. Topping is a stressful process, and if the plant isn’t strong enough or if it’s done too late, it can slow growth significantly. Since plant growth is exponential, any delay in development can have a direct impact on your final yield. In some cases, the stress from topping can even trigger early flowering, cutting down the plant’s size before it has a chance to bulk up. The key is timing and plant health. If you top a healthy autoflower at the right stage—usually around the 4th or 5th node—it can recover quickly with minimal setbacks. Pairing it with low-stress training (LST) can help shape the plant for better light penetration and improve yields even further. If you’re growing a fast-finishing auto, though, or if the plant is already struggling, skipping topping and just focusing on LST might be the better call.

Ja kann man, ich mach das eigentlich immer, zwischen Tag 14 un 16 toppe ich sie, sobald sie 4 Triebe haben und der stam 4 mm dick ist. Danach beginne ich mit dem LST, und da must du halt jeden 3 Tag oder so die Triebe wieder nach unten binden. Am Ende bekommt man eine kompakte Pflanze mit vielen colas. Kannst ja mal bei meinen Tagebücher vorbei schauen und dir ein Bild machen. Erträge sind auch gut denke ich. Bei meine letzten GhistbTrain waren es 130g trockene Buds nach ca 11 Wochen.

Yes.

Better to use LST "Low Stress Training" on them vs HST "High Stress Training", topping is a form of HST.

Yes you can, as the others have also said. But what you should rather try is a FIM. It does not slow the Plant down as much as a Top and if it is set too low it will be a cool Top like I found out in my Eternity Grow without sacrificing already grown nodes.

You can, but not the best option, you lose a lot a veg time while it recovers and with autos, any loss of veg growth will affect final yields adversely. Much better to train your plant with no loss of veg growth and uniterrupted yields.

you lose a bit of growth, and since vege time is not in your control, whatever you cut off is lost. if you cut off two nodes, you have 2 fewer nodes... fairly insignificant, but loss all the same. You can do wahtever training you want to autos. they are just plants.
