The roots are located in the space between the inside and outside wal, in a mesh bio plastics.
The open ends are closed with hard plastic, stone or metal.
This configuration makes a hollow tree, to be moved freely into any city.
The water use is small ..... but must be done by little pumps.
These City-Tree-Hotel stores CO2 in a durably way.
