Steel gutter system GM18

U-shaped

This gutter growing system has a deeper drainage channel measuring 40 mm. However, the gutter itself is not very high, measuring only 65 mm. The width of the drainage channel and the other bottom surfaces can be varied, meaning it can be adjusted to the preferred cultivation technique such as in tubs, peat bags, or on mats. For the peat bags, it is possible to construct a roof in the middle bottom surface.
