So I know that you should generally transplant aut...

You can transplant an Auto all through their vegetation life cycle. for autos you just need to make sure the roots have not hit the bottom of the container before transplanting or that they have not become root bound. I personally prefer straight into the forever home method but I have also tried out the other way and had no issues going from solo cup to 1 gal bag to 5 gal grow bag.

Never transplant a auto. They don't have time to recover and continue good growth. Their time is limited. So you don't want to do anything that stops growth. Start in final spot for autos

Yeah man just transplant it as many times as you need to . I usually do it 3 times and they never miss a beat . Watch a few you tube vids for some tips and the plant will only thank you for its upgrade .

I have never personally had a issue transplanting autos however I go from 1L straight to 10L so just once Just gotta be careful to not stress them to much Good luck with your grow 🙏

You'll be told not to uppot autos. Me, I personally think making a root ball in a small pot to start for for at least the 1st 10 days and let the plant take hold and she'll grow faster than starting out in a big pot. As for uppoting there should be no interference with the root unless it's root bound (roots all tangled together) then you'll need to break it a little but try not let it get to tat point. I had to break mine but I pushed mine past 14 days but there was no shock I just used a root stim and dosed the new bed I made and broke up a little and placed it down and ye, it's uppotting, but done right, you should just turn your pot upside down and place it straight into the bigger pot. Or use a plastic cup make a bed cut the cut with a blade Place the cup and throw the soil around cut the side of the cup and lift the plastic up and the soil will fall straight into place. (Doing this you'll only get 5-7 days in a cup) but transplanting or uppotting i call it cause transplant means you have to mess with the roots you ain't touching that unless you have. Anyways, 1-2L pots and do and 8 and then to an 11 or straight from your small into your big pot will make for stronger roots.. With photos you would uppot a few times autos are short window so once will do. Good luck.

transplanting when done correctly shouldnt be a major cause of stress but if you butcher it and mess with the roots too much it stalls the plant for a week or so and thats just a serious timespan for autos. so less is better imo, but make your own decision. i dont grow autos but i did years ago a couple of times and i sow into their final pots of 5 gallon at that time.

Typically, you want to start your autoflower seed in the pot it's going to finish in because they really don't like to be transplanted unless you're a master at it... any kind of stress to the roots will cause it to kind of hiccup and may impede it's normal grow pattern... and in autos, you don't have a lot of time to allow the plant to recover from any stress... I'm wondering why you feel the need to transplant twice? I've grown autos in 5 gallon containers and have germinated the seeds right in that pot - the seedlings look a bit ridiculous because they're so small in comparison but there's never been a problem or a reason why I would want to start them off in a smaller container.... So my answer would be no - don't do it... since you're going to transplant once, transplant it into it's final pot. Cheers!
