    Hi

    This is my first grow, from what I understand some dark period is good for autos. I have done 20/4 cycle. I understood that during darkness it grows more. I also understood that it grows during growth period and about 1 week into flower, after that it concentrates on the buds and stops growing, perhaps this is not correct?

    If that is the case (stops growing 1 week into flower), would it also be better to use 24h light after first week of flower? To promote even more energy to buds? I also saw on some places that during flower the darkness gives "longer" buds and having only light gives more dense buds instead of longer ones?

    Thx in advance for all help!

  2. Ive read and heard that you can go straight 24/7 light with auto's all grow, being that they'll flip and do everything that's dependant on the light cycle. Personally, ive done 20/4 and 18/6 with auto's, and ive never witnessed a difference. I stick with 18/6 throughout the grow and they turned out fine. Honestly, if youre giving them proper nutes and have the pH in line etc, you'll get good results. Im more of an archaist and prefer the 18/6 veg and 12/12 flower. I get good yields and good flower so why change it unless it truly does make a difference?

  3. I'm running 24/0 fine. I haven't found where anyone agrees on the correct light schedule. On a predominantly autoflower forum I visit they haven't concluded what a good amount of time but I've seen people yield 10oz a plant with 18/6 20/4 24/0 and all get good results. I've seen heisenbubble say 24/0 plants look beat up with that much but my and others plants are just as happy as others on other schedules.

  4. I have done 18/6 just cause it saves on your electricity bills.

    Autos light schedule isn’t critical but when flower begins I do give them 12/12. Saves juice and helps her ripen well.

    Ppl say 18/6 becuase it makes since for a plant to need rest .
     
  7. I haven't read anything that can actually prove that autos need rest.

    I haven't read anywhere that plants naturally grow under 24/0 even in Alaska that's only a short period of time . It's debateable but does common sense not tell you that anything not getting rest will be tired ....

    Neither have I, but what I noticed that applied same principle as full season seeds, they don’t mind it and in nature they would basically be like a full season but in shorter light cycles. Due to its origins, so mimicking that cycle would only enhance its ability but I’ve never done side by side , so maybe if I do get my hands on more auto seeds it would be worth testing .
    But I do know of many that do 24/0 and yield great.
    The canabis ruderalis portion on the auto originates it’s from areas s where light cycles would have Been lower or the season short hence its ability that was used in the original auto “low rider “ they do have or have been. Crossed with sativa and so extent hybridized with indica over time but all it’s origins always lead back to its original ruderalis roots

  10. But I don't think we are trying to recreate nature. Many 24/0 growers with impressive yield would disagree with you. I don't have humidity controllers and timers and stuff so I can recreate the natural growing environment but create the best possible environment.

    I don't think this is about common sense. I get that photos need the light cycle for induce flowering but when it comes to autos it isn't necessary and there's nothing to suggest that there is some optimal light schedule for autos only anecdotal evidence.

    I think there's an excessive amount of myth surrounding autos that leads to discussions like this. Super cropping, topping, and other methods usually reserved for photos have been done successfully on autos but people still say it shouldn't be done. The light schedule I think is irrelevant for autos and the autoflower forum I frequent hasn't reached a consensus on the optimal lighting schedule but yet there are plenty of grows pulling weight on various schedules.

    Ha bro no offense ; but you sound like your getting all your info off a grow weed easy page I saw not to long ago . Not bashing just being honest nowhere in the world do plants grow on 24/0 your auto guys can argue that, but I don't believe any veteran grower is going to run plants on 24/0 for the whole cycle ..... as about the nature aspect wouldn't you think if it's ben grown in nature for thousands of years that genetically If would grow better in conditions similar to nature .thats why so many ppl try to recreate a nature like set up

    You can't just change genetics unless your a scientist in a lab Ima leave it at that ..

    It’s why I think a side by side should be done to see what actually happens!!like I said I’ve seen some yield massive for a little plant and though I don’t dabble in autos much anymore my past routine was to treat it as a photoperiod plant. Knowing it’s ruderalis genes I can extrapolate that it doesn’t need 24/0 or even 18/6 but 12/12 would work as heck save me some juice!! That’s my reasoning
     
  15. That's cool I guess. Plenty of veteran growers on that forum run 24/0 successfully but I'm not going around telling people there is some perfect schedule for autos. But there's no proof that there is a perfect schedule for autos and as far as growing in nature we might as well all grow in soil because DWC isn't close enough to nature.

    Thx for all the reply guys!
    So it comes more or less down to that nobody knows for sure but anything between 18/6 and 24/0 works fine.
    And that is what I had guessed before as well from what I have read.

    The debate of them needing little bit of rest (4h or 6h) sounds reasonable since most living things on earth needs rest. But since this is my first grow I have no input about that besides it sounds reasonable.

    And it seems nobody has tried going from 4-6h rest to 0h rest when its flower time so I will let go of that idea and keep my 20/4 going for now.

    Perhaps someday I can try it and see if it would make any difference but since even 2 seeds are not identical in DNA and you would need clones to really test, besides exactly same environment for both and only changing light schedule I guess even a test would not say much :D

    Again, thx for all the replies and good discussion.

  17. Basically. It's all anecdotal and speculative. They will complete their cycle regardless of lighting.
