A vertical hydroponic growing system comprises an elongate housing 10 having a tubular outer wall 2 with a longitudinally extending slot 20 leading to an interior of the housing for holding hydroponic growing medium material. A plant held by the growing medium material grows out through the slot. The housing has an upper fluid inlet 36 for supplying a nutrient solution to the growing medium and a lower fluid outlet 38 for recovering unused nutrient solution. Within said housing interior is at least one transversely facing abutment 81 which sub-divides said interior volume into at least two longitudinally extending contiguous portions, including a first hydroponic growing portion and an aeroponic growing portion, the hydroponic growing portion being between the slot and the aeroponic growing portion. The housing has at least one removable panel for providing access to the interior volume of the housing for the loading of the hydroponic growing medium.
