Airpot

The side walls of airpots have at the tips of the outwardly directed conical holes. Thus, the root ball to restrict air flow. The structure of the inside of the plant moves to steer their roots in the direction of the open cone tips. The water content in the substrate decreases and the oxygen content increases, so dry out the cells in the root tip in contact with air, to some extent be curtailed by air. The compensatory response of the plant, this air conditioned by root pruning is an increased root growth. The root tips branch out in a short time, which creates a fibrous root system which favors the absorption of nutrients.
