I've heard of people using the 18hrs of light and 6hrs of dark and 20hrs of light and 4hrs of dark which light schedule works best and why? new to autos thanks what would the extra 2hrs of darkness do if running the 18 on 6 off?

I do 18/6 ... When I tried 20/4 and 24/0 I didn't see much of a difference in growth. There are also benefits to the darkness period.
I do 18-6 from what I’ve read a lot of people say it’s not worth the extra cost
