Can you put them under 12@12? They would ne under 400 DHS,150 hds

You could but wouldn't recommend it dude! 18/6 or 20/4 is the norm for autos

They will flower under any light cycle but your yield would be seriously affected at 12/12, like GG said the most popular are 18/6 20/4. I myself use the latter.
