Air-Pot 4″ WITH BLACK BASE
Air-Pots have unusual cuspated walls, sort of an egg box configuration, 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.
The plant responds to this “air-pruning” by sending out more roots to compensate for the loss which leads to a dense root system with a vast number of active white tipped roots.
