Yes! growing taller is possible. Let me tell you how then. Well your spine is always being put under the constant pressure of gravity so much so that over time it gets more and more compressed together... what you can do to prevent this from happening is by doing stretching exercises hat will stretch out the cartilage and larger the gap between the vertebrae in your spine.
After you have stopped naturally growing your growth plates will fuse together this is bad news because you wont be able to lengthen your actual bone length but you will still however be able to do stretching exercises like i mentioned above that shall make you taller... I don't know whether you can actually can call this growing or not.
But anyway this is just one of the ways you could do which will give you a height increase... in gotta know though that this takes a lot of effort and time.
