As far as the roots, you won't be able to tell til you transplant. But one good indication of big healthy roots is a big healthy plant. Pot size also helps determine plant size. And always remember ONLY ONE PLANT PER POT. All sharing pots does is increase your chance of having a problem, and makes plants fight for nutrients/space.
