About the Air Pruning Principle of Air Root Pot
Nov 15, 2019

Air root pot is circular shape with a perforated sidewall. One advantage of Air Root Pot is the ability to continually “air pruning” roots. The inward pointing cones direct the root towards the hole in the outward pointing cones where the air density in the soil is too great and therefore the apical cells at the very tip of the root dehydrate, or are air-pruned. The response of the plant to this air-pruning is to send out more roots to compensate for the loss, which leads to the build up of a dense and fibrous radial root system in a dramatically short time.

Short root systems with several root tips are far more productive than long root systems or big, fat roots. White roots with many root tips are most important for plant health.
