Healthier Roots
These planters provide air-pruning which prevents circling roots aka rootbound plants. When roots come in contact with the sides of a regular pot, they keep growing and end up winding in circles around each other. Because there's nowhere else for the roots to go, they get root-bound and eventually can't grow anymore.
In a BREATHE Planter or aeration pot, the roots come in contact with air when the roots reach the sides of the container. This tells the plants that there's nowhere else to go. Instead of circling, the roots stop growing and maintain a healthier, branched root structure.
This planter also allows you to go longer before repotting and reduces transplant shock (which traditionally happens when you move a plant from it's home to a new one).
