There will be controversy with that. Some great auto growers could well say nothing above 18 is required, but this site has also seen half kilo (dry) auto grows on 24 hours of light.

My auto I started on 18/6, and especially as flowering started I increased the light until it was on 24 hours a day.
I favoured 21/3 but, like you say more is better
