Changing light schedule 7 weeks into flower?

So 7 weeks into flower....

I started a job working the hours my lights are on.
Half of my flowers still have 50% white hairs, some slightly more. Trichomes are clear. So I feel that they'll go a few more weeks.

-My question is should I not mess with the schedule this close to the end?

-As long as I maintain 12 hours of darkness changing shouldn't bother anything right?

-Would I be better off to leave the lights off for 24, then turn 'em back on the new schedule,?

-Or adjust an hour or two at a time, maintaining 12/12, until the desired schedule is achieved?

Thanks in advance.

P.S. I can't wait to start my perpetual auto grow when these are done. The like the appeal of not worrying about 12 hours of darkness and one light schedule for all stages.
Cheers
 
Well the reason is I leave for work before 5am, the lights come on at 530am. I return home often 6pm, lights are off at 530pm.
So you see I have to tend to my plants during their dark period. It's a hassle. Waiting until Sunday for a good look with lights on is a drag.

A point I need to emphasize perhaps...I'm not changing 12/12 period, just need to switch the days to nights and nights to days.

Thanks for the interest.
Cheers
 
Sorry, I misread your first post. You're right: if you want to switch around like that, you would have to do it slowly, like an hour a day. But as you do it, don't add an hour to lights on; add an hour to lights off.

Now the other idea about 24 hours off is an interesting one, but I don't have enough expertise to comment on that. I did switch my plants' timing one time by doing it an hour at a time, but that was during veg. I hope someone else chimes in.
 
If you can't wait couple more weeks until harvest and you absolutely must change the light/dark pattern then do it half hour at a time everyday. When doing so it is better to disrupt the light cycle than the dark. Remember less than 11-12 hrs of uninterrupted darkness and cannabis start doing all kinds of funky shit you don't want at this stage. If I were you I'd just suck it up on this grow and not take a chance ruining my harvest and leave the schedule alone. Good luck!
 
Well it seems either the timer is broken or I screwed up. I got home from work early, so I started to open my room and realized before I got the door open the lights were off.
It's been almost 24 hours of darkness.

-Should I go to lights on this evening and switch like I wanted to?

-wait until morning and set to come an hour later than the old schedule?

-or keep the original timing because there's been enough stress with the lights being out all day?

Thanks in advance.
 
I'm thinking 8pm lights on. 8am lights out. Hopefully that will help deal with the heat as well. Better for my work schedule and family schedule.
 
Hey Calikid, that's funny that they got those 24 hours darkness, which gives you the opportunity to change the lighting schedule as you wanted.

Jeg had to leave the forum for family reasons. I miss him, too.
 
So a few days later...

I tell a friend my situation and how I think changing from lights on with the sun up to lights off during the day would have been better. He without hesitation asked what time my lights go off tonight. I reply 530pm. What time do you want them on? 830pm. He said ok when the lights go off at 530 wait until 830 (3hours)and turn them on.

Wait....WHAT !

He explained that a one time jolt wouldn't stress the plant enough to herm. But if I were to shift little by little, it would stretch out the duration of the stress over time causing it 2 hermie.

So after much deliberation, I decided to roll the dice. It's been 2 weeks since the the shift and all systems are go ! Better heat management.
No sign of stress. The flowers are finishing up great no nanners. Starting flush at next water.

Not a scientific study. But a risk was taken, results noted.
Maybe someone else may find this useful.

Cheers Californiakid

ps: I don't know if I would do it again. Very stressful watching and waiting to see if I screwed up. But so close to the finish I figured there wasn't enough time for seeds to develop anyway.

Really interesting information. I have always heard that it's better to change the time around an hour at a time.
 
What I did contradicts multiple standards. I broke 12 hours of darkness, and completely shifted day to night in one shot. All happened within a month of harvest. But the logic seemed good enough to try it. Lol So far so good.
 
Dude that's awesome! You're right about the stress factor, that alone would made me wait! But science is never advanced by reasonable people! Thanks for having cahones and jumping in the fire!
