If a plant is left in a plastic pot, roots grow outward and inevitably hit the wall of the pot which result in a few large roots wrapping and circling around the edges and eventually chokes itself out. This stunted growth leads to smaller harvest.
How can we maintain healthy root structure for potent growth and abundant yields of plants? Enter Air Pruning.
Air pruning is a technique that exposes root tips to relatively dry air which stops their growth. When the root tips stops growing, the root develops a series of lateral roots – secondary roots that branch out from the originals within the growing media and spread until they reach the thin layer of air at the walls. The cycle keeps repeating while plant is producing smaller, more fibrous roots through air pruning.
