YOU AGAIN!still it continues...you are wrong....photoperiod determines when the plant flowers............it's just science...i'm sorry....
phytochrome is what triggers many plants to start flowering...it is how plants see light.........i can't believe how many people don't now this......many plants are not photo period sensitive but most cannabis is...and it uses phytochrome to detect the change in photo period...
Phytochrome is a photoreceptor, a pigment that plants use to detect light. It is sensitive to light in the red and far-red region of the visible spectrum. Many flowering plants use it to regulate the time of flowering photoperiodism) based on the length of day and night ( and to set circadian rhythms. It also regulates other responses including the germination of seeds, elongation of seedlings, the size, shape and number of leaves, the synthesis of chlorophyll, and the straightening of the epicotyl or hypocotyl hook of dicot seedlings.
Biochemically, phytochrome is a protein with a bilin chromophore.
Phytochrome has been found in most plants including all higher plants; very similar molecules have been found in several bacteria. A fragment of a bacterial phytochrome now has a solved three-dimensional protein structure.
Other plant photoreceptors include cryptochromes and phototropins, which are sensitive to light in the blue and ultra-violet regions of the spectrum.
it's pretty easy...plants use phyto chrome to see light...when the photo period is right for certain plants......it triggers the flowering period....it's s fact...
more and more info on how the phytochrome system is used to detect photo period and trigger flowering........
Photoperiodism - Wikipedia, the free encyclopedia
Many flowering plants use the pigment phytochrome to sense seasonal changes in day length, which they take as signals to flower. Broadly, flowering plants can be classified as long day plants, short day plants, or day neutral plants.
Long day plants require a certain amount of daylight to initiate flowering (this was initially thought) it is now known that it is actually the night length that will influence the flowering, so a long day plant needs a short night which in turn will mean it has a long day. These plants flower in the spring or summer. Conversely, short day plants will flower when the length of daylight falls below a certain amount. Short day plants need the night to be longer and therefore the days are short, they will flower in late summer, autumn or winter. Day neutral plants do not initiate flowering based on photoperiodism i.e. they can flower regardless of the night length; some may use temperature (vernalization) instead.
A long day plant is a plant that requires less than a certain number of hours of night in each 24 hour period to induce flowering. Long day plants typically flower in the late spring or early summer.
A short day plant is a plant that cannot flower under the long days of summer. Short day plants typically flower in the fall of the year. These plants require a certain number of hours of darkness in each 24 hour period (a short daylength) before floral development can begin. Plants use the phytochrome system to sense day length or photoperiod.
A short day plant (long night) will not flower if a flash of light is used on the plant during the night. This does not occur from natural light such as lightning, fire flies, etc.
Phytochrome is converted to its active form by red light (660 nm), and its inactive form by far-red light (730 nm). Moonlight produces a greater percentage of far-red light than sunlight, so during the night the phytochrome is slowly converted to its inactive form. More phytochrome is converted in a longer night, allowing the plant to measure the length of the night.
Other instances of photoperiodism in plants include the growth of stems or roots during certain seasons, or the loss of leaves.

i didn't make this up it's real........
this is why I have a bloom room on 12/12.....right?
im sorry that you feel i am wrong, but infact i am right.
ill say it again
sexually mature plants ie: clones are ALREADY SEXUALLY MATURE!!!!!!!!
seedlings, and small plants will take longer man, they will continue to veg until they are mature. Once they are mature then yes flowering will begin.
i tell ya what, just for shits and giggles, ill start a journal, start a seedling, throw it into flower with my sexually mature clones, and prove it to ya
yall are just missing the most vital point of this debate.

I was going to say something similar...but what I think it come down to is ...Im pretty sure we all know when our plants are done, how many of you go exactly 8 weeks flowering if it says the strain should be done in 8 weeks?? I think more then time, we go by what they look like and how done they are. so I think the argument is more how do we keep track of time when flowering. I tend to agree more with bba's opinion on flowering, but all in all I dont think it's an issue of any one person being wrong, because we can all find ways to justify what we think is right.
YOU AGAIN!

the debate is: what day do you call day 1 of flowering?
all this talk of plant age and maturity is drifting from the original debate.
people were saying you don't start counting until you see flowers. others were saying you start when you first see flowers. it had nothing to do with the age of the plant.
there has to be a right and wrong. otherwise confusion arises.

dude my only point ever is that cannabis is photo-period sensitive....it reacts to long nights and short days by starting the flowering process...using the phytochrome system....i know you agree you seem smart....YOU AGAIN!

a seedling is immature..it is stressed by a photo period change at such a young age, it also has a different chemical make up then a mature plant so yes the photo period change will take longer to show the signs but they will come non the less the photo period will induce flowering but may cause some problems because of the stress you caused........
do this experiment...from seed veg 2 plants....germinate them at the same time only a week from germination put one into 12/12 let the other one stay in veg for another week and a half and then put it into 12/12 with the other plant...from what you are saying...the first plant that rotated in will continue to veg because it was not sexually mature, as will the one that stayed in the veg room...only this one will be bigger as it benefited from longer days for another week and a half ......now that the second plant is rotated in, they are both in 12/12 until they become sexually mature and then will both finish at the same time because they both start to flower at the same time regardless of the fact that one was moved into 12/12 a week and a half earlier because neither one was sexually mature they continued to veg regardless of photo period until they were ready.....
I've done this and it's not what happens...the one that goes in a week and a half earlier...will finish before the other one that moves into 12/12 later...because the photo period change will cause it to go into bloom.......
this is the whole reason why people flower seedlings or immature plants, is to start the flowering process.....to keep the plant small or for whatever reason,,,if it didn't matter when you started 12/12 people wouldn't do it early.........
again you are missing my point.
and i do not disagree with what u posted above
i do however think that you are still missing my point, so ill do my best to make it more clear, please do not take the caps as me being angry, cuz im not.
OK first off, your comparison is comparing 2 seeds...... and with what u posted above is absolutley correct, and i will not argue that with you.
by germinating the seeds at the same time.... each seedling will mature at the same time in a 12-12 or 24-0, light cycles INDUCE flowering, that doesnt allways mean the plants are FLOWERING!!!!
ok now my comparison uses 1 sexually immature seedling assuming its a female here, to 1 sexually mature clone taken from a sexually mature mother.
If i take the IMMATURE seedling, and a sexually MATURE CLONE, throw them in 12-12, since the clone is already sexually mature, it will begin flowering AS SOON AS THE LIGHTS GO 12-12.
If i take a 2 inch seedling that is NOT SEXUALLY MATURE, meaning we have no idea what it is, but in this case we are assuming that this seedling is a female. Since this plant has not shown sex, and has been put in a 12-12 cycle, yes we have induced flowering, but... we are not flowering because our seedling is NOT SEXUALLY MATURE, and in no way will it start to flower, until it has reached a mature state sexually.
since we have induced a 12-12 cycle, our immature plants will still grow in a veg state, not a bloom state, until it has reached maturity. Keep in mind by switching the light cycle the plants will go through a growth spurt just like a mature plant would, but it still is not flowering. once the plant show its sex, then its mature, and will begin flower production.
ok so recap
your comparison = seeds germ'd same date, but flowered a week and a half apart.
my comparison = 2inch SEEDLING vs sexually mature clones
i sure hope this makes sense now.
