The KoirPot™ Root Trainer plays a major role in the initial development of the roots. It is easy to use and made from natural materials. The walls of the KoirPot™ Root Trainer are permeable enough for roots to go through. As soon as the roots get exposed to air, the roots stop growing. The root buds then start to appear, developing secondary roots. Eventually, the entire pot will have a dense network of roots. After the roots are fully developed, it can be transplanted to the ground.
