Why you use air root pots instead of other pots
One advantage of Air Root Pot is the ability to continually “air prune” roots. Air pruning occurs when the root tip reaches a pocket of air, which causes the tip to desiccate and forces the root branch. Due to the rigidity of the sidewalls, woody plants grown in plastic containers often have more circling roots on the outer periphery of the root ball, while the Air Root Pot may allow for a more natural root system because of the effects of air root pruning. However, this effect depends on the length of time the plants are grown in the container.
