How can i achieve max. height (no peptides)

[DutchHtn]

I am currently 13 years old, I am now 178 cm or around 5 feet 10 i think (don't know for sure). I have had my major growht spurt, but i still need to grow around 10 cm or less for my max height. How can I optimize this and make sure i get my max height (i'm very scared to not reach it and be petite). Please help me and not insult me for being stupid or anything like that since this website has a lot of people who like that alot.
