turning night into day?

Hey y'all...total n00b on my first grow here with a quick question.

I have a 2x4 tent that I started flowering in about 6 days ago. I have realized that the 12/12 light schedule that I currently have the girls on (lights at night) is inconvenient for my lifestyle and I would like to flip-flop their schedule (lights during the day).

Is there a good way to do this? I am assuming that I should lengthen the night rather than the day. Should I do it incrementally over the course of several days (using perhaps a 12/15 schedule) or should I just do one long night?

This leads me to larger questions about photoperiod...is a 24 hour cycle necessary? Has anyone experimented with longer or shorter photoperiods, say 8/8 or 16/16?

I'm interested in this as well.

Especially the 8/8.

Just leave the light on until you want to switch to the time that suits you (easy as that). I dont understand how you can run 8/8 or 16/16 in a 24hr day. I start with 24/0 for 2 weeks then 18/6 for another 2 weeks then 12/12 until harvest time.
There is a reason to my method i can find for you if you wish.

What is the point of an 8/8 cycle? The way I look at it, we want to enhance the natural growth patterns that have been programmed into cannabis throughout its evolutionary progress, not trick it into thinking it grew up on another planet.

YES a 24 hour schedule is necessary, and you must have a 12/12 schedule during flowering.
If you need to reschedule your lights, then turn off the lights untill you want to restart the schedule, usually a person will turn off the lights and then turn them back on 24 hours later.

Thanks homegrown boy. I will just have a long night and get right on schedule.

My other question was just intellectual curiosity. Forcing equatorial to temperate species like cannabis onto endless light schedules is completely counter to their evolutionary adaptation as is much of what we do as indoor gardeners. While an 8/8 schedule might be ludicrous (I was simply using it as illustration) perhaps 12on/14off or 12/16 might provide benefit. I read something about an experiment where the photoperiods of a week were adjusted such that there were only 5 "days" and 5 extra long "nights" (or vice versa) and yields were increased but flowering period increased slightly as well.

I know that in many species of mammals including humans, circadian rhythms are actually longer than 24 hours (humans are more like 26 hours) but they are entrained by the 24 hour schedule of the sun. If left in a room with no cues from the sun, people's body clock will drift by a few hours a day until they are alert at night and asleep during the day (strange that we have a 26 hour cycle when we evolved on a planet with 24 hr days, huh?) It made me curious whether plants might thrive under slightly altered schedules as well. As I said, it is really an academic question not a practical concern because I don't want to adjust to an odd photoperiod. I will be sticking w 12/12.

i have never changed the photo period but i would suggest doing it in increments of like 30-45 min a day till you get the schedule you desire
hope this helps

It is not necessary to do that, it won't hurt the plant if he's only doing it once, besides, he is in flowering and by the time he gets the desired schedule he will have harvested already.

That extra bit of dark will help produce a little more resin, most growers i know including myself will give the plant 3-5 days of complete darkness right before chopping them down, you will notice the differnece when you go in to harvest.
