Gday all have a quick question can u change light cycle from 12 to 18 hours of light I have a couple of one’s flowering and have had to put seedlings with them the ones in flower have been for 3 weeks on a 12 hour cycle seedlings on 18 new to indoor Any advice will be greatly appreciated
It doesn’t matter a whole lot if they are all autos, which don’t care about the light cycle. If you want to change the light cycle, do it at your will. The plants won’t know the difference.

You need to stay with 12 hours if you have photos. An 18 hour cycle with photos will cause them to stop flowering and reveg.

OK thanks
Your auto seedlings will do fine with 12 hrs of light.
That’s great to know thanks
Agree with above, you do not want to change light to 18 on the flowering photos. I had one reveg once, and what a mess. And in case you don’t already know, make sure you have absolutely no light leaks during lights out.
