Herb light schedule

So im growing some basil, oregano, parsley, chives and cilantro.

What would be a good light schedule? I was putting them on 18/6, will this work or is there a more optimum one?

Also any general tips would be greatly appreciated !

Thanks

You can get away with 24/0 or 20/4. I grew herbs under a 45w CFL for 24/0
