27 and I want to grow taller?

I'm 27 years old and I'm 5 foot 7, and I'm curious if I can add at least an extra 1 to 2 inchs on to my current height. I'm 151 pounds and I workout 4 days a week and I get about 6 to 7 hours of sleep a night. Keep in mind I'm not looking to "apear" taller I want to actually be taller
