Is the photoperiod too short for my seedlings?

So I’m starting my plants indoors, it’s march 21st, and moving them outdoors in May, June. The natural daylight hours outside here in southern Indiana are at 12h:14 min long, plus the civil twilight witch is 56 min witch makes it 13h:10 min long. I’m starting them Inside under led lights and following the outdoor photo period so when I move them outdoors they don’t go into light shock or revegetation. So is 13h:10 min long enough to start my seedlings on under a LED light indoors?

Or should I put the light on 18 hours to start the seedlings and slowly decrease the amount of light per day until I get back to the natural photo period outdoor?

Start at 18 hours and work your way down to daylight time outside.
