Superoots
Air-Pots have unusual cuspated walls made up of closed
inward pointing cones and open ended outward pointing
cones. There are no flat surfaces on the inside of the
container to deflect roots and start the spiralling process.
The inward pointing cones direct the roots further outward
to the open ended cones where, because the air density
in the soil is too great, the roots dehydrate and are
effectively pruned. |
