light schedule

Does it matter when flipping into 12/12?
Think i've made a mistake. My lights are on 18/6 & come on at 14:00.
Stupid me 4got that I wanted my lights to come on at 20:00 so that my tent would stay warm during our cold nights.
Would it freak the plant out if the lights went out at 08:00 & didn't come back on till 20:00?

I've read that even slight light changes can stress your plant.

However, i accidentally left mine on for like 4 days in a row during flowering because my timer got switched to manual, nothing happened. Then on another incident, i had to box my plants to hide them and they were in dark for a full 20h. No apparent stress yet.

Yes, if you want to do this you need to extend the day cycle not the night. So i am going to put this in am/pm cause thats how my mind works, you come on at 2 pm, 18 hrs on means it shuts off at 8 am right?
So what you need to do is shut off at 8, come on at 2 (14:00) and then stay on until 2 (14:00) the next day, now you make it turn on at 8pm (20:00) till 2 (14:00)

Dark cycle is what causes the plant to know when to flower, that is why nothing went wrong with the light being on for 4 days.

Cheers. Making the mistake of not properly planning my light time, but now i'm just extending the lights on time till 14:00 then she will go to sleep for 6 hours then lights on at 20:00. Just hope she doesn't stress too much. Probs won't. Just me thinking.

I shifted mine by nearly 12 hours over a 3 or 4 day period and I havent seen any effects yet, that was last week.

Takes way more than a few minor schedule changes to stress a plant enough to cause it too hermi. More often than not when a plant hermis, it was going to hermi no matter the quality of care it received. Just more internet hype that causes undo stress too the grower!

In that case, when a plant is already in flowering, wouldnt it be okay to go like 16/8 for the rest of the cycle?

No it still need those hormones to build up to continue to flower, so you could in theory do 8 on 16 off, but your production would suffer. But 16 on 8 off would cause it to try to reveg.
