I am led to believe this system will produce a
double root system which will produce good veggies.

Sounds a bit like ring-culture. Here, the main food-getting roots remain
in
the upper container whilst finer water-getting roots grow in the lower
container. The lower container should be very well watered, whilst feed is
applied to the upper container.

A classic method for tomatoes.
