can i adjust the time my lights come on midway though a cycle?

i want to compensate for the heat outside by running my lights through the night and off during the afternoon. problem is right now my lights go off at midnight which is opposite what i want. can i move the time without freaking out my plants? btw i am in veg right now running 18 hours on and 6 off. thanks guys!

if your in veg mode u will be fine, i f%^& up my light cycles some days i do 18 other times i leave them on 24hours. they will be fine if u just switch

I'd think, because you're still in veg. You can just adjust your timer while the lights are on
to go off at the new time. A few extra hours of light for one day shouldn't be a problem.

i thought it would be ok, just looking for someone to tell me otherwise. i am going to adjust the timer right now. i guess i should have realized if i just run a long day i would be fine. duh! haha thanks guys!

good luck with it mate
