switching 18/6 from day to night?

okay so here's the deal, I have my light cycle on 18/6, 6am-12am and I am anticipating in the future I might have to switch my lights to run through the night during veg, due to cold temps at night related to grow room location. Probably for sure during flower.
What would bethe best way to go about this? I want to maybe eventually run them from 5pm-11am, when i want to switch Would It be okay to just keep the light on for 35 hrs all the way to night cycle I want for veg? (6am-5pm next day)

I have no experience but many people keeps lights on 24/24 so keeping them on for 35 hours would be fine.
And it's 6am-11am next day so that would be 29 hours.

Yup. Just run a really long day...

Absolutely no problem doing that bro. Go right ahead and make the switch!

I agree. Constant day cycle then switch to your desired time.

I run 7pm-1pm and my flower cycle runs 7pm-7am.

7pm fits into my life perfectly for lights on.

Why kind of outside temps you usually have? Is this why you run your lights at night? I live around the 47th parallel and it is already starting to get cold outside (& in) and ik debating lf I should only run at night

I run my lights at night because of daytime temps. In summer NO A/C will keep anything down at day. 120F in the hot months...

What about for cold temps at night?anyone run their lights at night specifically due to cold temps? If so can anyone give me some examPles of their outside temps? Right around now-winter?

I always run my lights at night due to the colder temps.

Now 11C at night outside. Running temp in my room without fan controller 15C. With fan controller 20C-28C I try to maintain 24C.

During winter. Outside temp as cold as -8C.
During winter running I generally have to block off 2 of my 3 passive intakes and allow air passively under my closet door.

I utilise an 80w 2ft tubular heater, and a 221w dehumidifier.

These 2 items along with block 2 passive vents keeps my temps stable during winter.
