shortest light cycle for flowering?

what is the shortest light cycle you'd recommend for flowering with optimal growth?

my light schedule got fucked so i basically decided to take a loss on a few extra hours so i can fix it over night. i've read 10/14 is okay and should speed up flowering by a little but i was wondering if that is recommended at all or is a minimum of 12/12 a must?

Im not sure 100% but under 12/12 like 11/13 your weed can finish faster but not gain weight and anything above 12/12 like 13/11 can hermie BUT ppl have done both and been successful so its a preference thing id stick to 12/12

What happened to your light cycle? 10/14 is fine. Prefer 11/13 over that tho
is anything under 10/14 recommended?

my dad turned it off cause my grandpa is bitching that i run the lights. grandpa is just a cheap ass since we split the electric bill equally throughout the whole house. he always bitches and complains about us running something though can be a ceiling fan, the tv, the ac in the past, etc.. we pay our bills though so really it is none of his concern or worry. he's always been like that though and it goes deeper with money issues that he is having due to him loaning money to my aunties who can't afford to pay the bills.

it would only be for like 1 - 2 days only not permanent for now at least. i'll try 10/14 and if im still wide awake by 12am then fuck it might as well stay up and run a 11/13

Gotcha. You can go all the way down to 6/18 if you wanted, but that's be wasteful i think. 10/14 is the lowest I'd go. Maybe 9/15 at the end of flowering to be conservative

will it hurt the plants if i run opposite? say i run the full 12/12 but then they only get a short dark cycle before i flip so basically in the next 48 hours i would of had a longer light cycle over all. meaning they would have exceeded the 12/12.

cause the way it went it 6am-6pm on yesterday then 6am on, 7am off, then i got darkness until about 4pm so basically i had a super long dark cycle and when i flip back on tomorrow i'd have a super long light cycle.

It still needs 11 hours of darkness between days to flower. I would just resume the regular light cycle. It won't mess anything up

7am to 4pm - off period
4pm to 6pm - on
6pm to 6am - off

Am I right with this?

Then resume at 6am to 6pm on

what you mean? like just run it now and let it go as is? i could tbh the biggest issue with that though is i have to sleep XD grow room is right next to my bed and massive light leak. plus i have to water but i guess i could just water it later at night when i come home cause on this schedule im basically watering the plants at like 9-10pm with about 4 hours maybe of lights on. i work nights but the lights would come on at maybe like 2pm i think so basically if i water sooner i get light leaks every 2-3 days.

hmm idk wtf imma do i mean if i do flip to the regular cycle it would of gotten 12+ hours of darkness overall timing wise would be off though so it would be like running a double light period back to back if i did my math correctly but with 3-4 hours of a dark cycle so not too back.

today it was 6am-7am ON 7am-4pm OFF 4pm-X ON
yesterday 6am-6pm ON 6pm-6am OFF

so basically yea about the same. so basically it's 6pm right now just shut um off and resume tomorrow? literally only got 2-3 hours light today though

Resume tomorrow. It wont hurt you. I'd be afraid of messing up more trying to catch up on lighting. You missed a day of light but that's fine.

I've accidently left lights on for 24 hours once, I gave it a day of darkness as my panic solution. Didn't skip a beat.

thanks yea at this point im just like fuck it whatever happens, happens just gonna run um for a few more hours then off into darkness then resume the normal schedule. they should be fine i just wanted to squeeze out every bit of growth but it's okay hopefully it doesn't happen again anytime soon.

Yea shouldn't be a problem at all. Just make sure you have enough a dark period before the lights come on tomorrow

What were trying to say is You dont want less than 12 hours darkness , especially the first few weeks .
It doesn't matter if you've only ran the light for 1 hour it's the DARK period that matters. To initiate flowering the plant must get roughly 12 hours of uninterrupted DARKNESS.

Check out gas lantern method . Ppl keep there plants vegging by interupting the darkness cycle.

If you shut lights down now at 3am they can't come back on until 3pm or later .
6pm is after 3pm

There is no way to really quicken this plant up or we would all be doing it with great results - 10/14 for first half of flowering then 14/10 on off for secind half to harvest is the biologivmcalky quickest i can get but were not talking by much maybe a few days at most so really not worth it over 12/12.

You can work out your kilowatt hours per week in money then pay your granddaddy a little more and that will fix that. Then you get him growing too and chill that old grump out with some dank ass nature.

Old folk dont understand weed but they soon come round when their arthritus is gone and they have some minging old chicks hassling them for some weed :-)

idk about the whole 10/14 stuff i just read that. my friend tried it and i tried it for a few weeks only so i can't say much about it plus his plants hermied. as for the grandpa he will never come around thats just how he is. doesn't matter if im growing weed or a damn tomato. he just grumpy thats how he is i think he hates my family cause he treats us differently then my aunties ( his daughters ) and my cousins but we don't care lol.

i ended up going to bed at like 9pm so i got about 6 hours at least of light before i just reflipped so now they are back and running normally.

Bud will flower slightly quicker at 10/14 and finish sloghtly quicker with longer light say 14/10. None of this is worth bothering with though and these plants will not finish much faster or slower reguardless.

You could actually use 14/10 the whole cycle but it would be a little slower to change to flowering.

Again none of this really makes much difference just use 12/12 as its there for a reason, we would be talking a fractional amount any other way in reality.

The most heqlthieat plants finish the fastest - skills are what you want not light cycles :-)

yea i mean im not super worried now because my light cycle got fucked yesterday so it was only a 1 time thing and i just wanted to push as much light per hour i could within the night but im content with 12/12.
