When does flowering actually begin?

shall i post the correct answer again perhaps?
I think you should qwizoking :-)

Hey Ausweed, why don't you keep taking cuts of your plants, after you flip 12/12, yet before it's flowering in your eyes. Have fun with the re-veg growth OK
:wall: :hump:

Sorry, but this is wrong.
Really, when did you last complete your degree in horticulture ??

quite simply a plant is in flower once the hormonal change is taking place to tell the plant to flower/reproduce. Since you would require more than the human eye to determine this hormonal change the next identifying element that your plant is in flower is when you see your flowers forming.

just because you dropped the time on a light does not automatically mean it is flowering, it takes time for the plant to recognise the change and hence begin the hormonal changes etc..

Also as flowering periods differ from plant to plant so too does the time taken for the plant to actually be in the flowering stage, some plants may well be into the flowering stage when the 12/12 is initiated other phenos can take a week or two or more

As long as the mother plant has not shown visible signs of flowering you will have no problem putting the plant back into veg, you obviously have not done it.

Also, have you never seen what a dope plant looks like when it begun to flower and went back into veg.....pretty easy actually champ, stop smoking and try growing...

the problem i have with saying when you see flower clusters forming, it's kind of vague and up to the person to determine exactly what they think is a flower cluster.. i mean, is it a flower cluster when you see two pistils forming together, 3, 4, 5, 20? see where i'm going with this?

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.
just a slight question, where you say a plant will flower once it is mature irrespective of light schedule...... I am not sure this is true, especially considering commercially grown weed is grown from mother plants that have been in veg for years.

Ok put it like this, a jacaranda is in flower when ? When you see the purple flowers yes ? So too it is with marijuana, there is no difference, the only reason guys say a plant is in pre-flower is because the plant has not begun to put on weight as it were, it is in my opinion quite easy to visually see that your marijuana is in flower, once you see those pistils or balls he or she is putting on her flower show.....

No offence, but it seems that most of the guys struggling with the flower question have only ever grown marijuana or a few veggies, if you have studied horticulture the answer is quite simple.

Almost 25 yrs. indoor exp here bozo! I think i know what re-veg growth looks like lame. I think there's one person here who is fresh out of school, and who has no idea about growing cannabis :o

This is getting silly. The term 'flowering' is a convention. We are not a bunch of biologists, we are hobbyists and commercial growers. The commonly accepted way to use the term is the same one breeders use when pitching their wares: weeks flowering = weeks from flip to 12/12.

This convention may not be perfectly accurate from a horticultural perspective, but being accurate would require a sampling of hormonal levels in the plant, and that ain't happening.

The point of language is to convey useful information. Technically speaking, the sun doesn't 'set,' our position on the earth rotates away from the sun. Are we supposed to never talk about a setting sun?

This is completely not true.
Try this for yourself:
Pull a plant out of 12/12 after 5 days, put it back in veg lighting.
Report back what happened
Lol

Lol - I take cuttings regularly from flowering plants, root them & they become mothers back into veg.
It takes a bit to root them & for them to revert back to veg, but it's an easy process.
Here's a Doublebubble that was cloned @ 8 weeks flower.
What's the issue again ?

So we have established that it is quite easy to put a flowering plant back into veg, are you ok that it wasn't what you thought or are we still debating ???

mate, some dope plants can flower up to three seasons........they don't all die once flowered. So going back to vegetative mode is very easy, I don't know why ou think its so not able to happen.

maybe because of your 25 years indoor experience you are so used to just pulling the plants when done.....

Please read the posts again! I'm not saying taking cuts from a flowering plant won't work. JESUS CHRIST man! Come on now. Look how excited you got lame
I've cloned from flowering plants once or twice in my lifetime, but i usually like to preserve a strain differently :-) I've re-veged many a plants.

What I'm trying to make lame realize, is that the plant will go through a re-veg period/growth, if it was put into 12/12(flowering),then brought back into veg, after a while.
MY POINT:
Why would the plant(or cuts in this matter)go through a reveg period, if it actually was NOT in flower, like lame keeps saying.

I'll repeat this in another way:
Take a plant that has been under 12/12 for say....5 days. Put that plant back into veg lighting. Most strains I've tried this to, WILL go through some reveg growth for a bit.
Ausweed seems to think that it wouldn't happen, because the flowering plant wouldn't have had flowers on them yet. He is wrong.

Like I posted before lame, I'm fully aware what re-veg means and is. Everyone growing weed knows of this. It sounds to me, like I was probably revegging plants before you were even born son! Lol

I should have qualified this; this is when growing outdoors and daylight hours are or can be more variable throughout a season. This wouldn't apply to strict lighting schedules on an indoor grow, no, it wont flower without a change in the schedule.
