Re-vegging plants

Hey! I'm preparing some plants for oudoor and I had them on 12/12 from seed to sex them.Should I put them 24/0 now for them to re-veg or should I just put them outdoor and how long would it take for them to reveg? Would they reveg outdoor with 15h of sunlight?

Thank you for your anwser!

Just to be safe i'd give them a shot of N and run them 24/7 lights for 2 weeks then, put them out. Good luck!

Will do that! Thanks!
