Had a class one time where we studied plant roots, in nature the root mass vs top mass, most thought it close to equal or maybe more under neith. Growers try to turn that on its head, by supplying what the plant needs, thus less roots out hunting and more energy to top.

In your case, 6 footer outside, in four gallons of dirt, bet it takes a lot of care. But thats why your there.:jointsmile:
