The growTOOL Pe-Stop is a plug for drilled holes with ุ 4mm. These can occur when a water spin resp. its adapter is removed from the supply hose. To prevent these holes from deforming so that they may be used again or the nutrition solution from spilling out those holes are closed with these PE-stops. Of course they can be removed as well when needed.
