what in the actual fuck are you talking about. took you too long to google that. *yawn*

the moon is like 1 lux on a clear night. i have never ever been outside in the complete dark.
Well discrediting me isn't helping @cannabisweedPotNerd at all with his question.. But for the sake of argument, if I left a cfl on in my grow room through my entire dark cycle with the rest of my lights on 12/12 would my plants still flower? Now supposing I was in veg, turning my lights on and off at random times every day, would that not stress out my plants?

discrediting you is stopping the spread of bogus info.
for the sake of argument? how about for the sake of shutting the fuck up?

Minimum. 20 hrs... Maximum.24 hrs. Even at 18 hrs they will eventually flower..
This is false. There is much research on this.
Some of the places where most of our strains come from, have 14-15 hours max daylight, and don't flower.
Genetics determine this. Know your strains, this can be dialed in.

Why would you do that?

What about putting it out same time in morning and pulling in at night at same time?

How much light does a photo strain need so it doesn't go into flower?

Min and max

So I'm going to put plants outdoor from from shelter around sunset in morning then put in shelter 2 hours and 15 mins from sunset at night so it doesn't get wet. How many hours will a photo strain need so it doesn't flower when I put in shelter which is a dark area

Thank you advanced
just try to keep a schedule

EDIT: yeah do the same time thing, and do it in accordance with a proven schedule, like 18/6 so you can rest easy, set an alarm on your phone or something

Why not set up a cfl, or better, inside? Do you have bugs yet from going in and out?
muddy footprints and soil and crushed perlite everywhere omg i would hate doing that.
once the plants are mature they can handle the environment, provided its not a hurricane..or if its flowering you could tarp it at night

Indoors or outdoors, a light cycle is a light cycle. 18 hrs of uninterrupted light will keep a mature plant in veg. You will throw some pistols when mature and maybe give one the impression of flower is beginning, but it wont flower. Though stranger things have happened, they haven't happened to me in many moons of growing.

Telling some 1 that their plant will flower under 18/6 is ludicrous I've seen many mother kept on a 18/6 light schedule for More than a year and they don't just miraculously start to flower under this light schedule.
@afghanking @HydroRed @Dr. Who @tyler.durden anyone got a link
Everything I've ever read states that an 18/6 light cycle will not allow cannabis plants to flower. I just searched this phrase, 'will mother plants flower under 18/24 lighting'. Every site on the first page agrees with this. I'm on a tight schedule, so I've always done 24 hours for all veg including moms and clones, then right into 12/12. If anyone is disagreeing with this, it should be simple to find credible evidence to back up their position. I could not...

But you only get like 10 hours off direct sun light? Talking about direct sunlight

Did I say it miraculously flowered..no it started at 9 months and went to 13 months.. I'm just stating what I know to be true.. I am not a liar.. So call whoever you want I don't give a fuck!!!
You're probably just confusing flowering for pre-flowers. There is no way you had photo period that flowered under 18 hours of light.

You're not going to find any credible evidence ever concerning cannabis specifically because of the federal illegality of it is preventing major universities from committing time and resources to study of the plant.

For the time being ask a botanist or someone with a lot of plant biology knowledge, usually you can apply what you learn about other plants to cannabis. While it's a unique plant it is still just a plant and grows like one.

I don't know about that. A lot of credible knowledge comes from places like Israel, where they consistently take a scientific approach to studying cannabis, both its growth and its effect on humans. Raphael Mechoulam first identified the THC molecule and many other cannabinoids, and has conducted the most comprehensive, government sponsored research of anyone, imo. Also, now that it is legal on the State level in many areas, we see many applying a scientific approach to cannabis. The scientific method is the best route to credible information, and it is being applied to cannabis...

Once again you are wrong!! I have been growing for over 46 years.. It wasn't only one plant one time it was several plants
over many years. I don't need you to tell me what I saw or what I know..

I can't tell you what you saw or what you know because I'm not you but what I can tell you a cannabis plant flowering after nine months under an 18/6 light schedule just sounds like a really big and absurd claim. Did you document this freak plant for us?

Glad Israel is progressive in at least one way. Of course such studies would be relegated to a country where the majority of people would be against it but it can happen anyways because the laws are so loose there.

And how do you know this? Read it? Or have you grown plants for over a year? Real world experience is what I'm talking about... not what I read or heard!! Sorry no pics. Polaroids don't last that long... and getting them developed would have meant Federal prison. This was 1974-84

Ok see though we can call bullshit on you because the burden of proof is on you. You're claiming you had a plant flower under an 18/6 light schedule. No one else has experienced this but you and you expect us to believe you based on what you say and now you're making your story even less believable.

Polaroids DO last that long, I was born at the turn of the 90's and still have Polaroids of myself as a baby. You could easily still have them.

Plus getting them developed wouldn't mean federal prison, self developed Polaroid cameras were avaiblibe at the time and not that expensive. If you had the money to grow weed back then you had money for a Polaroid camera. To top this all off it was more than thirty years ago?

All these facts compound to make your story simply unbelievable and you get all mad at us when we doubt you.

It'd be like me coming on here telling you all that I had a plant that produced four pounds under a single 150W CFL in a 2x2 scrog, but I didn't take any pictures, it was ten years ago, but you just have to believe me because I said so.

No one else has had a plant flower under 18 hours of light, no one else has documented it, so we can only assume you're either A. don't remember correctly or B. lying.

And you also need to clarify what you meant by your plant flowered...did it start making buds OR just shoot out pistils? Was it indoor or outdoor? Is it possible lights were cutting off somehow?

Regardless, I personally think you're just not remembering correctly. As I've said, your unique claim needs some unique evidence, otherwise no one here believes you and you just come across as a petty liar when you get all defensive about it.

Edit: To answer your initial question, I've both read and seen the effects the light cycle has on the plants flowering. I've been growing for close to a year now and have three grows under my belt. My personal experience doesn't change the validity of your statements though, that's just you being immature and trying to push the onus of this debate onto me in an unfair way because it distracts from your claim of flowering a plant under eighteen hours of light. Keep the questions relevant.
