Hydroponic cultivation consists of growing plants on inert substrates with liquid mineral nutrient solutions. It has recently become popular for home-growing plants in limited spaces and for large-scale greenhouse production of crop plants. It is also a valuable tool for the scientific investigations of plant mineral nutrition. Despite the importance of mineral nutrition in the carnivorous syndrome, there is no recent report on the potential usefulness of hydroponics as an investigation tool for studying mineral nutrition of carnivorous plants. The goal of this study was to evaluate the growth response of carnivorous plants of the genus Pinguicula on a peat-based and a rockwool-based hydroponic set-ups under various conditions of mineral deficiencies.
