A perfect demonstration of the advantages of using Air-Pot containers right from propagation.
The two Sequoia seedlings are 30 days from germination. The one on the left from an Air-Pot seed tray the other grown in a standard tray. Already the Air-Pot grown one has had its tap root air pruned and is growing a mass of healthy lateral roots. The tap root on the other has hit the bottom of the tray and has developed a J root deformity. As a result it will never be as strong a tree.
