I just love how you think that becase you are giving it more than 12 hours of off cycle
It wont go intersexual. Any stress can cause intersexuality in plants. Be it heat stress, moisture
Stress, stress due to photoperiod..

You are overconfident of your knowledge, yet poorly informed. GL

hi first grow.. and just thought hey.. why the fuck not..

like most of us on our first grow.. we read read read and do some more reading.
so i know enough to understand what happens with the plant and why it does what it does.. so when it came to flowering ... i asked myself... like im sure we all do..
more darkness? better response?
well through my research no one person can say that all cannabis plants will or will not. it really depends on that plant.

so i will testify to a 13/17 light schedule, yes im aware that its more than a 24 hour day.. but who told these plants a day was 24 hours? well im deceiving them and telling them days are 30 hours.
i'll keep you guys updated..View attachment 1341049

correct me if im wrong... but would that not just stress the hell out of the plant confusing it everyday, technically every day it would be sending the plant back and forth into veg and flowering

well please do help ... please do inform!!! but why... why why.. and why insult? when if your knowledgeable about something i'm not? aren't i supposed be learning ? lol thanks tho.. for being offended by me being overconfident. i guess?

and yes i do realize there's PLENTY of ways you can stress out your girls... but i only stated my won't unless i give them less than 12 dark simply because there's no other stress occuring to them??? and then you somewhat hint to me that im wrong but yet don't inform me how i could be stressing her out??? umm ok lol

here's what i DO know.. if i give her more darkness ... its not stress... if i keep the schedule the same.. its not stress... if i add one hour on top of the 12 for light it won't stress if i keep the schedule the same.. my temps are great and well i do have pictures posted if you would like to judge my plant?? i see no stress occurring but hey what the fuck do i know.. im new right?

how would it send the plant back and forth thru veg and flower cycles??
as long as your plant is getting 12 or more hours of darkness she stays in flowering.. i keep her with 17 hours of dark... if she were to go under 12 hours of darkness only then will she return back into veg. state. then resulting in stress.. i don't see how you guys think this would stress her out.. she's literally 1 and half weeks from flushing ... if this was harmful in anyway.. wouldn't i know by now? lol wouldn't she have 'been' stressed out..? i would think so.. she started with 13/17 since day one of flowering... and was on 18/6 light cycle for veg. ... i mean she's looking beautiful from my view.. but shrubs first might tell me im wrong and then not say why.. so let me hold my breathe .

i know if i were going to alter my plants flowering cycle (stating with new plants ofc) i would put the research into using the uvb bulbs during the morning and sunset hours. apparently its going to be in the next grow bible and can extend your flowering light hours to something like 15 while increasing resin and yield.

some crazy stuff out there.

There is something called the Circadian Rhythm, AKA physiological clock. The fact that the physiological
activity follows the day’s course has been known since antiquity. Including the activities of plants (the rising and
lowering of leaves, the opening and closing of flowers). These phenomena have been experimentally studied since
the 18th century. The Parisian astronomer DeMAIRAN detected in 1729 that the plants’ movements remain
even when they are kept in constant darkness.

It was necessary that animals and plants developed mechanisms in the course of evolution to measure
time and to react to the change of day and night, since the day-night-rhythmic is one of the few constant
parameters of our environment.

No one "taught" these plants the day was 24 hours. It is instinctual, based on years of evolution. Well-founded
evidence exists that time measuring occurs.

It is not necessarily the light dependent reactions. But temperature dependent. Studies show that lower average temperatures
inhibit enzymatic activities. The rule of thumb says that the activity increases twice when increasing the temperature within the
physiological range by 10° Celsius.

If you increase the off cycle you decrease the amount of cellular respiration that happens per time. Basically, the same amount of work
will be done in the 12 hours of off cycle as the 17 hours of off cycle..... Sounds like a waste of 5 hours to me.

Didn't mean to insult.

LOL I was gonna come here forwarding you to a LC for some math lessons haha.
Provided you have a timer that will do it, it would be interesting.

I would be highly surprised if the "ideal" length of a day is exactly 24 hours 0 minutes, 0 seconds but rather genetically the plants are "programmed" to operate on this.
Interesting thread, really made me think.

EDIT: On second thought, if anything wouldn't it be better to have shorter days (say 12/8 ) not longer assuming veg was 24/0?
Wouldn't anything more than 12 hours of light inhibit full flowering? And wouldn't a shorter recovery (night) time be more beneficial over a long one considering I see more growth during ON times.

Plant flowering is signaled by the off cycle. Not on cycle. So the plants are actually effected by the off cycle
more than the on cycle. Just because you see growth more readily in the on cycle (probably because thats
when you're usually in there anyways) doesn't mean that is what effects them.

hmm yes very interesting. i shall read more up on that.. and 0 time is wasted my friend lol plant is still on schedule if anything its somewhat ahead of schedule... she's doing great and i haven't a complaint.. i really did this experiment to see if it was a success.. next grow i will have a control.. and compare the 2.. we shall find out who wins then.

Tahoe did this and did have some success, he also had some limiting factors from severe nute burn though

Why would anyone alter what has been proven to work for decades.....sounds like a bunch of shit just to stir controversy....or are you gonna attempt to change mother nature next?

While I am sure someone will say it is the same thing, it is not the number of hours of darkness that trigger flowering but instead the number of hours of light diminishing. A flowering hormone is present during all stages of growth. This hormone is sensitive to light and is rendered inactive by even low levels of light. One there is not enough hours of light per day the hormone will do it's thing and flowering begins. So technically it is length/number of hours of light and not hours of darkness that cause a plant to not flower or to flower ... but again, I am sure that some will say six of one, half a dozen of the other .. but in photoperiod plants, which cannabis is, flowering is controlled by how many hours of light it receives and as long as it is enough to inhibit the flowering hormone flowering will not occur.
