I have been reading various threads that touch on the ideal size of a grow box and was wondering why bigger isn't always better from the perspective of quicker growth. As I understand it, ground growing produces the quickest growth because the roots have plenty of room to run, but one runs the risks of having their nebari get away from them due to the rapid growth. Alternatively, using a shallower grow box will allow one to control the nebari better, but at the expense of slower growth. Putting availability of space and cost of soil aside, wouldn't we get the best of both worlds if we used an incredibly long and wide box that was shallow?
I've heard people say things along the lines of "the box is too big for the tree" and I'm not sure what that even means. All things being equal, why not plant a very young and small tree in a 50"X50"X4" grow box filled with the best bonsai soil for the tree/climate to grow it out?
