Flash Babylon auto questions

I was just given this plant today. It sprouted from seed 5/29, so it is 12 days old. My grow area is already on 12/12 light cycle. Will it hurt to put this one in there too? The plant came from a very close friend.....I love having good friends. This is also my first grow with good seeds. Please take a look and let me know what you all think! Thanks in advance for any and all advice
