Seedlings when to change light cycle

I looked everywhere for it but I could not find any post that said when you go from 24 hours of light to 18/6 hrs.for seedlings? Thank you all for your help and time.

Ive always done 18/6 from beginning. Only difference is intensity is lower while seedlings.

That’s what I heard of people doing also. I was thinking maybe when I have my first 2 sets of real leaves? But if we can do it from the beginning then I’m sure I could change it over anytime. Thank you for your reply. I appreciate you taking the time. Have a good afternoon.

Light change no big deal…UNTIL…switched to 12/12.

keep in mind, 12/12 schedule will make plants double in height within few weeks. Even with topping.
If in a grow tent or nosy neighbors…this could be a problem.
