Autoflower training

Tell me is it true that autoflowering plants are better not to be trained? I heard that it is too much stress for them and can affect the final result. Thanks.

Setup. Strain - Autoflowering

Of course you can train. Success depends on what training, what genetic, what enviornment. Nonetheless, if you overdo it or with wrong timing you can mess it up, because the auto's do their stuff. To get a serious answer you have to choose a strain + setup and test how they take what training, because you could speed her up or slow her down depending on kind of training and your timing. To be on the safe side... LST (~up until stretch/preflower depending on the strain week and environment W3-5)+ defoliation now and then when it really is to crowded or lollypopping, probably won't mess up anything. You can take a look around on several diaries. How it turned out.

these are not the autoflowers of the past...they have been bred and crossed so many times with only best stock being selected to cross and re-cross that they now act more like photoperiod parents and can be trained as such but you are on their time schedule and timing is crucial so you don't stress them and stunt them... breeders like Night Owl Seeds have bred their plants yo grow plants with naturally formed canopies so i never lst or top my autos... strategic pruning leaf tucking and i will tie branches to open things up but to cause the plant to alter its natural growth like lst.

Ps I actually didn’t like the result of topping with Titan F1 Auto, the buds ended up too close to the substrate and caused some issues. Here’s that run if you’re curious: growdiaries.com/diaries/189987-royal-queen-seeds-titan-f1-grow-journal-by-yan402

Yeah you can train autos, same idea as photoperiods, just with less room for mistakes. It’s not that they’re fragile, it’s just that their timer doesn’t wait. So if you stress them too hard or too late (like right as they flip), they don’t have time to bounce back. But if you time it right and go gentle — early LST, maybe a top, light defol — they handle it fine. I’ve trained autos across multiple runs without issues. This one’s a good example: growdiaries.com/diaries/216050-royal-queen-seeds-apple-fritter-automatic-6-grow-journal-by-yan402 Full LST and defol, no stunting, solid yield and bud structure. Strain choice, timing, and how you treat them makes the difference, and personal preference too. Whether it gives more yield is debatable. You could argue LST alone is enough.

Training definitely helps produce a more consistent yield - less weaker buds in lower areas, more evenly-distributed mass of flower etc etc. It probably doesn't do much for overall yield, and in some cases can actually reduce it. You lollipop too much and you definitely reduce yield. You train too much and limit your vertical growth, that'll also cause a reduction in yield. primarily user-error stuff... with autos on a biological cock, rather than us changing dark cycle length, you could argue things like topping would not be wise as you cut off growth that cannot be recuperated, but if you only cut off 1-2 nodes, it's not a huge effect, either. Most people will probably cut off more larf when they lollipop and not recognize that as loss of yield while doing it. six in one, half dozen in the other... autoflowers are simply marijuana plants that go into flower based on some biological timer. That can make for differences, but not nearly as many as people attribute tot eh plant. e.g. autoflowers are not 'faster' - total nonsense they take just as long to flower when comparing apples to apples. and just to cover a false negative too -- they don't yield less per sq ft - **indoors only** outside they definitely have a lower yield potential per arbitrary area measurement. dli and atmospheric carbon sets the ceiling, then user error reduces from there. uncontrolled environment or pruning shit off that is helpful etc etc. weird shit based on pseudo science doesn't always have a negative effect but definitely can.

LST is ok. HST is normally not ok.

Ultra is spot on. With experience being a big factor.That and strain are the things that will determine the outcome.Indicas stay short and quat so for the most part arent great vfor training but the majority of strains out there are hybrids from 50/50 to 70/30 either way,indica or sativa but if you lack a decent amount of experince you'll stunt an auto if you train or traansplant it.Take no notice of people saying its best tpo transplant as it isnt if you don;t have experience.Put thise autos down,haha.Do photiperiod then you can do allk the transplanting and tarining and fucking it up all you wannt as it all the time in the world to grow back as you just give it more veg.You are the fat controller.

Potatoe, potato. Experienced grower well versed in the arts 🎨 is a different kettle of fish from a nooby on 1st grow. Correct and proper training reducing stress to a minimal therefore limiting the time lost to stress response. New growers often try to train autos stunting growth for 3 weeks then wonder why buds are small.

Hi also ich trainiere meine Automatics immer und habe immer gute Ergebnisse. Ich toppe und danach LST. Wärend des gahzen Prozeß wird auch immer mal wieder entlaubt. Kannst ja mal bei meinen Tagebücher vorbei schauen

Hey there great question. I agree do not do any high stress stuff like topping the plant you can do all the lst and bending branch’s you want. Although I don’t think the reason is they can not handle stress. I think the reason you should not top autos is because they are a gamble you have no idea how large each plant is gonna get and you have no idea when it will start to flower. It’s very possible you can stunt the plant just a small amount durring a seedling and the plant starts to flower but you don’t know it yet and you top it after it started to stretch. If the plant is stressed at all like being stunted from over watering when you go in to the stretch the plant will not be growing fast durring the strech and won’t grow very many bud sites. Now if the plant is already stunted and then it gets topped aswell right around the same time it starts to go into the strech then the plant really won’t do much at all that’s when you see those plants with like 1 little bud on them. I grew the fastbuds pound cake not that long ago and it didn’t go into the strech till around day 40 after it came out the soil so that plant I would have had plenty of time to top it but along time ago I got some free seeds from rqs some f1 auto seeds and all 3 of the seedlings started showing signs of flowering and started growing hairs when the plant was only like 3 or 4 inches tall So sense it’s a gamble with autos that’s why they say don’t top them…. Now maybe if you found a strain of autos that was consistent and you grew it a few times and they always get large then you would be fine to top it sense you know what it will do This is why I like photo plants
