Zaltan,
In most cases thal minor will not limit your growth in height. Most of the males in my family have thal minor and they are near 6' tall.
Most men gain the majority of their height between ages 14 and 21. The best thing you can do to make sure that you reach your maximum height potential is to get adequate sleep, eat nutritious whole food (fruits, veges, proteins and calcium). Adding more vitamin D and zinc along with calcium, magnesium will help too.
Best,
Sharmin
