Ps not saying that you no nothing either lol to elaborate that is to all with some of these simple noob questions use something called google it might help just saying

Flowering begins when you switch to 12/12 for fuck sakes! Seems like there is only one guy who doesn't know how to count the days of when a fucking plant is flowering!

lol, subcool has even said right on this site that flowering starts at the flip to 12 / 12.. so much for that theory.
*LIKE*

BOOM! Question answered!

I might add that technically, a plant does NOT reach sexual "maturity" UNTIL it is ABLE to actually produce pollen or become pollinated! (I skipped the technical terms too).

I don't count anything. I veg until 14 inches high then flip to 12/12. I then flower until the trichs tell me to harvest. 50 days or 90 days, who really cares. The girls tell me when to feed, water, and flush. No calender in my garden. Guess what, I don't have any of these petty debates. I have more important stuff to concern myself with.

If someone can't grasp the fact that we have always, even before the internet, considered that the flowering phase BEGINS when we INITIATE it(12/12). Than there's absolutely no hope for that person.

the few things I think speeds up flower times.
maturity: when the plant no longer shows opposing nodes (staggered) if a seedling, or clones are almost always ready to flower
light schedule: some people give a 24 hour dark period, then "flip" to 12-12. This supposedly re-sets the plants internal clock, and forces it to flower a little faster. This run i subtracted 15 minutes a day, going from 18/6 to 12/12, this took 36 days and when i was at around 14/10 I was seeing signs of flowering
Temperature: low temps will slow a plant down, I try to keep roots @ 65+ always, (shooting for 68) and the canopy at a 70-80F during the day , 60-70F at night

genetics are a different ballgame, this will obviously effect flower time, but isn't relevant to what the question is

while a plant is flowering, the stress it undergoes will increase flowering time. Say you decide to supercrop, top, or whatever during flowering. This will end up making the plant take a little longer to reach ripeness

taken all that into account, I try to get the plant to show signs of flowering ASAP, by whatever method seems applicable to my situation at the time. Sometimes I might have to flower the same strain a little longer depending on how I stressed it during flowering, but the way i gauge it is by when it starts to show signs of flowering, AND when I flip to 12/12
the way I see it, is the closer i can get the same plant to show flowering signs to 12-12 flip, the better job I have done in speeding up the flowering process. So many things effect the plant, there's no way I could talk about it all. I'm not a super horticulture pro or anything, this is what i've gathered from the crops I've done up till this point and is the way I see it, from experience. Just hinting a few details might be off but I think this is a good way to gauge flowering times and when you could harvest, I always use a microscope though, for safe measure.

I also do a selective harvest, chop the top 1/2 or 1/3 or 2/3, then let the bottoms go an extra few weeks. It's amazing what the rest of the plant does in such a short amount of time, try it if you haven't!

I didn't read but technically its flowering the first night of 12/12 if mature

"The signal is initiated by the production of messenger RNA (mRNA) coding a transcription factor called CONSTANS (CO). CO mRNA is produced approximately 12 hours after dawn, a cycle regulated by the plant's biological clock. This mRNA is then translated into CO protein. However CO protein is stable only in light, so levels stay low throughout short days and are only able to peak at dusk during long days when there is still a little light. CO protein promotes transcription of another gene called Flowering Locus T (FT). By this mechanism, CO protein may only reach levels capable of promoting FT transcription when exposed to long days. Hence, the transmission of florigen -- and thus, the induction of flowering--relies on a comparison between the plant's perception of day/night and its own internal biological clock. " Each plant has a different length critical photoperiod, or critical night length. This same concept applies to our beloved plant as well as all plants despite when they flower...for the most part

There are three physiological developments that must occur in order for this to take place: firstly, the plant must pass from sexual immaturity into a sexually mature state (i.e. a transition towards flowering); secondly, the transformation of the apical meristem’s function from a vegetative meristem into a floral meristem or inflorescence.. An external stimulus is then required in order to trigger the differentiation of the meristem into a flower. This stimulus will activate mitotic cell division in the meristem, particularly on its sides where new primordia are formed. This same stimulus will also cause the meristem to follow a developmental pattern that will lead to the floral growth.."

Flowering starts with pistil/bud formation....or the switch to 12/12 on a mature plant....it does not have to have flowers to be flowering..once its on 12/12 its technically flowering with the build up of hormones, which build up the very first night....

This is expressed in the 730nm light range (called PAR lighting). This nanometer range of light is strongly expressed at "dusk" in nature. Testing with the use of 730nm supplemental lighting has shown that plants can.
A: Express flowering faster
B: Shorten flowering time
C: Increase overall quality and yield

lol can be done easy I did it with some bag seed for a fun experiment and I ended up with a plant about 15cm tall ( growing in small pot) with a crown nug bout 4 grams lol was fun lil experiment coz didn't really do shit besides make sure it had water and had less then 12 hrs light that was it no ferts nothing and she grew fine lol weed called weed for a reason it grows fairly well and can also adapt very well yes some strains are a lot more touchy then others but I suggest if you can't grow a plant can't tell it's sex then you should not grow UNTILL you've done enough research save the trouble and keep buying you weed UNTILL you know the basics of what your doing and how you gunna do it preparation is the key to a great grow over an alright grow you'll just be letting your self down putting all ya hopes into a grow only to be let down severely to what you imagined it would be... Thinking and hoping you'll get a 6" plant and then you end up with plant 2" anyways good luck with ya growi and expanding your knowledge :)
I grew a few plants 12/12 FS. Im not asking if they will grow.
I'm saying the plant isn't flowering when the seed pops from the ground. Just because the plants in the flower room doesn't mean the plant is flowering.

Lol yea sorry bro just get so confusing on these topics with everyone throughing in there 2cents because it's such a good damn simple one lol no pun intended bro SO FOR ALL YOU SIMPLE MINDED FUCKS THAT TRIED GROWING BEFORE YOU KNOW THE BASIC FACTS= fail flowering - indoor grow flowering will happen WHENEVA THE FUCK YOU WANT IT TO HAPPEN PEOPLE mean switching to 12-12 or less 10-14 as I said iv grown a seed on 12/12 before it even sprouted out of the dirt and was done fully in about 12 weeks from regular bag seed to bud and I also have a seed planted at the same time still vegging In a decent size pot so it's nearly been in veg for 6months and I could keep it in veg for another six months again...and p.s sexing isn't just about the pistols my plant that been vegging for 6months showed it was a girl prob at least 3months ago it's the pre spur that the pistols come out of that shows natrally in veg or some lil nut while start if it's a male iv herd of people vegging plants for few years as mother plants for there clones so again indoor grow while only sex when you make it's conditions change to trick it to think its flower time otherwise it could potentially grow in veg for years and outdoor will happen natrally with the changing of the season can't stop those girls or guys when it's there time
I just can't believe there's people out there growing a marijuana plant already and don't have the first clue what to do and how it grows lol

If that we're the case then how would one determine the beginning flower if growing outdoor ? There's no 12/12 flip under the sun....

The answer was mentioned above, when flower pistils and petioles are multiplying. Read up on your botany and horticulture

I've always questioned this flower time thing myself...
Me and 3 other growers pass around clones and grow under similar temps, conditions, et; more or less
anyway seems flowering times are consistently longer than advertised, except for maybe Cinderella 99

I can't argue either way or add anything except its a pretty safe bet to add about 7-9 days to harvest from most advertised dates, and that includes most vegetable seeds (and I've lived where summer days are pretty long)

Well......just an FYI: 99.9% of growers consider flowering to begin 1st day of 12/12 talking INDOORS! Duh!
If you can't except this, or need to compare outdoor to indoor to make yourself feel better, well.........
Good luck wit dat

*edit
OK, maybe not 99.9%, but, MOST :wall:

thats right duh !!! To say your flowering begins once the light schedule changes is not right. There is no difference between indoor and outdoor the measurement is the same, once the plant begins to multiply its flowers it is in flower, not just because you switched the light s to 12/12, again then how do you work it out for outdoor......now who needs the brick wall......ohh and speak to those growers you mention and I guarantee it is no where near 99.9% as you claim......stick to your theory and mediocre weed is all you will ever have

So it would seem there isn't one answer to this question. The answer appears to be determined by 3 factors: maturity of plant, indoor/outdoor and if we are counting on observable changes (pistil/bud formation) or internal hormonal changes resulting from a change in photoperiod.

12/12 from seed would give entirely different results, as would forcing flowering of an immature seedling. So this wouldn't give a general rule able to be applied to all. We should be discussing in terms of mature plant (as an immature plant will need to become mature prior to budding, immature plants don't flower).

As for outdoor/indoor, I'd suggest that flowering of outdoor plants is again based on plant maturity, with influence of photoperiod - though not dependent on exact 12/12 daylight hours. If a plant outdoors is mature, it will begin to flower irrespective of photoperiod (assuming it is provided with a short enough* photoperiod)
*this could vary greatly depending on a range of factors, including latitude, strain and aspect.

Decided on if a plant is flowering based on either physical/morphological observations vs internal hormonal changes is a subtle one. They aren't mutually exclusive, with one dependent on the other. This I guess is up to the grower - but would relate to photoperiod most of all, and again based on plant maturity.

All this arguing about which is 100% correct, when people use vastly different growing styles seems pointless. To determine the answer, it must be considered with the growers methods.

When I say i am 40 days in flower, it does NOT mean that It is 40 days since I switched to 12/12.

I determine flowering not by the presence of pistil (as that is just an indication of a plants sexual maturity), but when the beginning of clusters, also known as flowers, form.

You can contact just about any breeder, and they will tell you the same thing. When u order ceeds, and the description says 55-60 days, that is not from the 12/12 flip. It is from when the plant is actually flowering.
Sorry, but this is wrong.
