Hydroponic and vertical farming technologies are widely used in many countries, including Turkey, for the cultivation of products such as tomatoes and strawberries. In the case of commercial hydroponic farming, plants are grown in solid substrates such as coconut peat, rock wool, vegetable trimmings, wood shavings, and poultry feathers mostly in fertilized water-flowing channels containing essential nutrients. As an alternative to this method, hydroponic systems, aquaponic systems and aeroponic systems are also available. In hydroponic systems, the roots of plants simply float in the nutrient solution. In aquaponic systems, vegetative production and freshwater fish farming are combined. The waste water of the fish is used to feed the plants. Aeroponic systems, on the other hand, refer to a structure where plant roots stand in the air and take water and minerals from the nutrient solution sprayed on them. In commercial crop production, one of the most widely used systems among hydroponic systems is the nutrient film technique. With this technique, in which plants are grown in gently inclined channels in which a thin layer of nutrient solution flows, oxygen-free roots can be prevented. The aim of this study is to compile information about hydroponic vertical farming technologies, which are rapidly becoming widespread today and which we think will be economically effective in the future, and to compare the advantages and disadvantages of these systems.
