**Another Question, but Related**

I've read that root development translates into above soil plant development - so robus roots mean good things for a plant, correct? Well that is obviously something which requires space. Yet the goal of the garden-plan I'm looking into is to use a minimal amount of floor space - no more than a 3' x 3' area. This combined with the goal of having a packed SOG garden, makes me wonder - could the lack of diameter in the pots (the plan is to use soil) be compensated for by simply making them deeper? Will the roots go downward as this is the only are for them to go, or will it be much more of a struggle than being allowed to grow outward as well?

Second, that kind of nutrients and soil medium encourage the best root development? I'm open to hearing about organic or chemical possibilities at this point.

Your help with these and the other questions I've posed is most appreciated.
