“Height Growth”

Hello I am 27yr male and I am 5'7 (170cm) right now and I want to grow just up to 172cm. Can you tell me how to grow without surgery? I did stretching 20min everyday and I ate right but and everything but I don't see results. I heard someone say you could gain height by decompressing your spinal column daily by using inversion machine, is it true? What are other effective ways? If you know please tell me.
