In both cases the gutter must have the capacity to channel all the drainage water away from the growbags in order to avoid a situation of the growbags standing in water. The gutter must have a slope that will allow a quick removal of the drainage water. At the end of the rows there should be a collecting pipe in order to remove the drainage water away from the plot (growing area). Disposing (or collecting in a recycling tank) of the drainage water is essential for the plot’s healthiness.
In the case of a hanging gutter, the structure’s weight limitation must be considered when the growbag type is chosen.
