Even when it says 0% growth, your population still grows. It just grows at some tenth of a percent. I know, because I had a game where my population growth was 0%, and after a few years I saw my population go up 1.
The only thing you might do is transport people to that planet. The more people you have on a planet, the more will be born. It won't raise the % at all, but if you keep transporting people off planets that are full, your populaytion will grow a bit.
