Can I slowly move my 12/12 schedule to an earlier time over the next 2 two weeks?

Hello,

My work schedule's changing and im 3.5 weeks into flower. Can I move it by ~8-9 minutes per day over the next couple of weeks so my lights turn on 2 hours earlier and if I can, will it harm my ladies? Thanks guys!

just turn them off early one night and make sure its off for the 12hrs they should adjust pretty quickly and not hurt em might shock em for a couple days but no worries

Just change it to what you want it it to be, It will only be fucked up for one day so nothing really to worry about.
I bet you don't even notice difference in them.

Worst thing that can happen is they hermie and you end up with a lot of feminised seed.

done this a few times, be sure to extend the dark period and not the light period for a 100% successful next day reset.

^ This.

Sometimes there are rainy days, lots of clouds and no sun. Its all good.

Thanks guys!

Your suggestion would require a lot of unnecessary bulb clicks which you want to avoid. Nothing pops a bulb faster than twirling the timer with the ballast and bulb inline. It takes about 3 weeks for a flowering plant to revert to veg mode when you change the light schedule from 12/12 to a veg time. So there is no problem with changing the timer at one time. Better, for one day, they receive more light over a 24 hour period than less than 12 hours.

Good luck, BigSteve.
