Adjusting darkness times

I've been flowering a plant for about a week now, the dark peiod is from 6pm to 6am but in about 3 weeks i plan to start flowering another two plants but i'd prefer them all to be dark from 8pm to 8am. so basically i'm just wondering if i could change the dark times and what effects it would have on my first plant.

I'm guessin just givin her an extra 2 hours one day wouldn't be too nice but could i say up it by 5min each day over the next 24 days? what effect would this have?

Thanks for the help :)

try moving your timer 10-15 minutes a day until you get it at the times you stated...
as far as I know 10-15 minutes difference won't shock or change their feelings too much, ...others will follow...latewood

I would reccomend making the cahnge all at once.

Otherwise, the plant will sese the days are getting longer each time you do this.

Make the switch all at once and do it pronto.

One day wont change her chemistry plant wide...

But several days will.

Thaks my thrity two cents :)

interesting, harddon, i wasn't saying to change the length of day, Ish stated he was in 12/12 so I meant to move the sttg's from 6 to 6:15 start and finish. then move the sttg's to 630 to 630 and on and on each day until, he got to 8 to 8 we're talking about a 15 minute swing per day for about 8 days...I believe the task can be accomplished either way.
Whatdaya think.

Ok...have the plant see the "morning sunshine" later by 15 minutes a day...

I see what you meant.

Hmmmmmmmm....

I am not sure...although what would concern me with that is that it is happening for 8 days.

8 days is a long long time in the short life of an MJ plant.

I cant say it would be bad because I dont know this.

But logic would indicate otherwise. Logic would predict reduced yeild and faster harvest time.

I would still prefer the one shot switch.

cool

Thanks for the advice guys think i'll make the switch tomorrow when i finally get them in their new house
