I am also interested in 12 on 24 off. Actually i have a Critical Kali Mist ''CKM''by delicious seeds, i loved that plant and took lots of clones like 30+ and it was the healthiest of all, sweet structure, i loved it from seedling, sometimes if u rub against stem or leaves, the smell would remind me of actual cheese, not the strains, sweet. But when it came to flowering, days passed, and she grew, i had other strains in there too, they were budding while she was just growing crazy. Funny thing, i started wrapping my cabinet with its branches like in a square fashion. 9 weeks in 12/12(11/13 last 4 weeks), not even a single bud on that. Then one day leaves started wilting. I gave her a high dose of ferts, and in 3 days she died. Now i wasted all that 30+ clones, but kept one
. All because i hve never smelled anything like it before. But still have that anger inside me of her not flowering on me while i loved her. So m in revenge mode
I transplanted that clone in 1L paint bucket. Now for next grow, i already have an experiment planned. Before that, i did extreme topping, i mean like 60 tops, but here is the thing.... It had more branches, but a lot of them were so weak. Very uneven growth after topping, sometimes after topping the branch will just ignore the topping and still grow in one branch. So i don't like it. This happened to CKM as well. So i like the look and appeal of the main central cola. And the idea is to get multiple main colas. So thats why i cloned too much of them . So CKMsss 30+ clones discarded, next grow plan is 3 paint buckets, the big ones, it says 20kg on the buckets. Each bucket has like 8 to 10 clones.
Now here is the Good news, its been 2 months since all above, and here is what i did to that CKM to make it flower, it is still in a 1litre bucket. I would take that plant, it was 2ft in height. i would put it in a separate cabinet for 24hrs in dark, then back in my original flower cabinet, i would do this again and again. sometime i forgot to put it back, so it stayed maximum for 3 days in dark, then back in flower, i did it for almost a month, and finally CKM showed flower formation, which i never saw before, currently m in 9th week, i also wanted to do another experiment. i bend its main stem 90 degree, to place it below / under my flowering plants, where there is no light at all, but thats the only place i could find, so one bend 90 degree, and another bend was like 170 degree, felt bad, but i wanted to see weather it dies or not. And guess, that plant is still going and i can see flowers are forming there, though extreemely small. but the thing is i made it flower clearly, by randomly putting it in dark. I have to say that she is a hell of a survivor.
Though it might take couple months more, but i dont mind, because it is negligible to me, and my main crop is growing above its head very nicely.
To contribute to this discusion, i want to say that yes no more than 12 hrs will keep it in flowering. not sure what will happen above that, i think it will put it in veg, but increasing dark time upto 3 days randomly has forced it to flower. its been a month since i have not touched it, its in 12 12 but its flowering, not growing vegetatively, while before that it kept on veg growth even after 2 months in 13-11.
Now i really want to know about 12 on, 24 off. Regarding people saying mixed thoughts about 14-10 or 13-11, some says it works, some says it doesnt.
here is what i think, the ones who say 12/12 give more yeild say it because they are usually harvesting near breeders mentioned time. While the ones saying it reduces yeilds, are also doing the same. u get my point, but as compared to the ones who say 10/14 worked and yeild was good, i believe they are not lying, they are telling the truth, the missing piece is they are letting it go longer than breeder mentioned time.
It makes sense in another way too. Suppose by increasing darkness to 14 hours, you are behind 2 hours of light everyday, thats what 160 hours for a 80 days grow, if we convert it to day to add, its 16 days so yeah two weeks more maybe and you are at same light hours during the whole grow and i belive this will work, right now i have two grows coming in 2 different cabnets, one is at 9 weeks and one is at first week. I finally took the decision yesterday to change both of them to 14 off 10 on, because same plants, my very first grow, i was in such a hurry, i quickly changed my time to 14-10 and this time iam far far behind with 12 12. though in my first grow i choped them at day 73 or 74. look, with 10-14,90% pistils were dark
dark brown and receded back at day 75 with your typical mostly cloudy few amber few clear trics theme. Now this time 99% pistils are still white at day 61 today with 12/12. you tell me which one is better. well since yesterday its 14-10 and iam keeping it for now. Will see the difference again between my current 9 week grow and 1 week grow. 12-12 is way slow for me. 14-10 was way faster, but i never got the chance to give them more time. This time, i will harvest in parts, and after that, next experiment is straight away reveg of the current grow.
