So if I move plants from 24/0 indoor light schedule outside in the 14/10 outdoor schedule and interrupt the night cycle with a flash light for 5 mins every night would they stop them from flowering? If so how long should I keep interrupting the night cycle until they'll be okay and adjusted on there own? It's may and I'm in Northern California like I said earlier it's currently 14 hrs of sunlight a day right now.

Gradually cut the hours back to 14 before going outside. That is the safest thing to do. Big swings in the hours of light is non optimal.

Hit it right on the head. Every week or so drop your timer down an hour, gonna take at least a month or so to do so from 24/0. Change it to 22/2, then in another week or so change it to 20/4. Rinse and repeat until you're indoor veg light cycle matches that of the outdoor light cycle. You can do this for the rest of the month and still have enough time to get them out around the beginning of June. Putting them outside now will cause them to re-veg and that's always a total bummer.
Next year I recommend starting your clones and/or seedlings outdoors in a miniature greenhouse. I did this last year and had great success with it. It doesn't need to be anything big or extravagant, just make a little hoop out of chicken wire and cover it with some visqueen. Mine was about a foot tall, a foot wide, and close to three feet long. The greenhouse actually did a great job of keeping them protected from the elements, regulated humidity, etc. I had great success doing this and by April I was ready to transplant into large pots.
Best of luck with your venture my man.

Did you use lights to extend the length of day? With seedlings you have a little grace period of 4-5 weeks until they are sexually mature, but clones are already there.

5mins with a flashlight is not likely to work. clones need continuous light for a couple of hours after dark to keep them from flowering. I try to keep clones on 18/6 from cutting it until june solstice (longest day of the year) & then turn off the lights...best of luck

Sure didn't actually, for me it wasn't really necessary because I was living in Southern California at the time. I just looked up a daylight schedule and that helped to determine when the best time for me to plant was. After the winter solstice, the amount of daylight we get starts to gradually increase until the summer solstice when the amount of daylight we get starts to gradually decrease as the days go by.
I'd pop my seeds in mid April when the amount of daylight was 14 hours, however you may even be able to get away with starting them in March. Even though there's only 13 hours of light in March, the amount of daylight increases. Flowering won't be triggered until the daylight starts to decrease day by day. It all depends on where you live though, you'll need to look at the amount of daylight you get and when.
For Southern California, starting seedlings outdoors in March-April is optimal because they'll continue to veg until a little past the summer solstice. Eventually the plants will begin to flower at their own pace when the amount of daylight starts getting shorter and shorter. It's been years since I've grown outdoors so I forget the exact month the girls would start throwing out pistles, I think it was around July for me. Harvest usually came around September or October, depended on the strain.
Just keep in mind that your light cycle doesn't have to be exactly 12/12 to trigger flower. Flowering is triggered by your light cycle getting shorter, not so much the amount of light you have. That's why going from 18/6 or 24/0 down to 12/12 will trigger flower. It's not the 12 hours of light/dark that triggers flower but the fact that the light cycles are getting shorter.

That's why starting outdoors with seed can be less of a headache than using clones. If the seedlings are started outdoors, they'll be used to the outdoor light cycle and won't flower/re-veg on you like clones will.
When I'd grow outdoors using clones, I'd either root the clones outdoors in the miniature greenhouse I mentioned above or I'd start them inside and gradually drop the light cycle from 18/6 to 14/10. Dropping the light cycle has to be done very gradually though, or you run the risk of triggering flower. That's why I stopped going 24/0 for veg, because no matter what I would do the girls would always flower and then re-veg. However, starting veg at 18/6 prevented this for me. My first outdoor grow I'd say over half of my plants ended up revegging on me.

I don't use lights except for vegging my Spring crop, so I haven't had any experience with moving from inside to outside in the Spring. But plants needs some down time to rest. I vegged my Spring crop at 18-6. But even 23-1 is better than no break at all. The folks that veg clones at 24-0 are trying to get as much growth as possible, but they may not be the ones who will be growing them out, so they don't have to deal with the consequences.
Not trying to be a troll but if that's the case then how do people do the gas lantern routine? In case if you didn't know that that is its where people do 12 hours on 5.5 hours off 1 hour on again then 5.5 hours off. They basically interrupt the night cycle to keep plants from flowering. They even say u could use a cfl for that 1 hour on since it's ment to just interrupt the night cycle. People do it to save electricity mainly. So I'm honestly gonna have the respectfully disagree. Especially since I've heard stories of people not being able to get there plants to flower due to small light leaks during night cycle. Only time will tell tho...

And hour is 12 times as long as five minutes, so. . . . .
It will work to interrupt the night time, since the length of night is what triggers the plant to flower {or veg}. But light induced stress is a big cause of plants changing their name to Herman.

I was always told that cannabis creates a hormone at night build up of this hormone induces flowering. Hormone is not created during light keeping it in veg thus the reason some flower sooner than others and others need less light to stay in veg its like hitting puberty kinda some generate more hormone faster during the night then flip some need less to its all genetics

Auxin, gibberelin ,cytokonins ??? Not sure If that's 100% how its spelled but yeah plant hormones lol
