Development of the Ontario tube ... In 1966, the Ontario Tube System expanded from small trials to large scale production ... A variety of paper tube materials were tried ... The (final) alternative was an all plastic tube and this could be readily extruded at low cost. The two most important biological considerations in this tube were the longitudinal split which could allow the tube to fall off as the seedling diameter increased and the overlapping of the split edges to contain the roots inside the tube during growing.
