There's no way anyone can possibly answer that. We don't know what strain you're growing, what your environment is like, the soil and nutes you will use, if you're going to do anything like topping the plant or using scrog, etc there are so many factors and even if we knew all of them we could only give a rough estimate. Should yield pretty big good though I think. But if you want the biggest yield possible you should dig a hole in the ground and put your soil in and the roots can go as deep as they want.
