Hydroponic cultivation of raspberries (Rubus idaeus L.) is becoming increasingly interesting, particularly because of the precise control of growing conditions. The purpose of this thesis was to determine, based on literature review, which hydroponic systems and substrates are most suitable for raspberries and how hydroponics affects growth, yield, and fruit quality. It was found that substrate systems using coconut fibers are most suitable for raspberries, as they provide a good balance between air and water and offer mechanical support. Substrate-free systems (NFT, aeroponics) are less suitable due to the risk of root desiccation in the event of a power outage. Research has confirmed that an air temperature of 23 °C and optimal fertilization increased yield by approximately 30%. Changes in electrical conductivity (EC 0.8–1.6 mS/cm) did not significantly affect yield, indicating that raspberries are adaptable to a wide range of EC values. The literature is not entirely consistent regarding fruit quality—some authors report higher antioxidant content and better color, while others report lower sugar content, depending on the cultivar, temperature, and light. Primocane cultivars are more suitable for hydroponic cultivation, as they do not require a long dormancy period. A lack of long-term studies on the lifespan of hydroponic raspberry plantings and research on economic viability has also been noted. Nevertheless, we can conclude that hydroponic raspberry cultivation is feasible and, under the right conditions (the right cultivar, a suitable system, and controlled temperature and fertilization), can provide a high quality yield.
