Possibly, if you plant them at the right time of the year for your area. Cannabis had done just fine on it's own for thousands, maybe even millions of years before humans began cultivating it. If the soil is good and if they get enough natural light and water, they will indeed grow without your help.

But most people prefer to make sure they grow, and thrive, by making sure they get what they need, even when nature doesn't provide.
