The Groove Tube
System is unique in its design. Sharp grooves in the
side walls discourage roots from circling. A large drainage hole promotes
air-pruning and dramatically assists in the development of additional
auxiliary roots. The added depth of the cell means greater exposed
surface for regeneration of roots when transplanting.
The Groove Tube
System trays are vacuum formed of high-impact, polystyrene
plastic, and can be re-used.
