Hydroponic plant cultivation and examples of practical use.
WEIDENTHALER, Jakub
The aim of the thesis is to present the different possibilities of hydroponic cultivation. The basic principle of hydroponics is explained in the literature review. Furthermore, the individual possibilities of practical cultivation of plants in domestic production as well as in large-scale production are presented in detail. The advantages and disadvantages of the most used methods are also explained. The main advantages and disadvantages of hydroponic cultivation are assessed. The biggest benefit of hydroponics is growing plants without the need for soil. Hydroponics is thus also suitable for indoor growing in the home. It can thus be used in urban areas for vertical cultivation, where there is a huge saving of space. In view of the loss of agricultural land and the deterioration of its quality, hydroponics seems to be the crop of the future. The saving of water consumption, mainly in recirculation systems, is also a major advantage. But there are also clear limiting disadvantages. The biggest problem is operating costs. In 2022, during the energy crisis, the cost of energy is proving to be the most limiting factor. Most hydroponic systems need a constant supply of electricity to effective run.

Study of drugs intake by lettuce
Amrichová, Anna ; Zlámalová Gargošová, Helena (referee) ; Řezáčová, Veronika (advisor)
The aim of this thesis is to analyze the content of selected groups of drugs in cultivated lettuce. The theoretical part includes a chapter dedicated to the drugs used, their use, physicochemical properties, and their impact on the environment. Other chapters focused on analytical methods for determining drugs, hydroponic cultivation of lettuce, and some parameters of ecotoxicological tests. The experimental part began with the optimization of the QuEChERS extraction procedure. The optimized procedure was then applied to hydroponically grown samples of roots and leaves of lettuce containing selected groups of drugs, which were subsequently analyzed using liquid chromatography – mass spectrometry. The experimental part also addressed the ecotoxicological impact of different drug concentrations on hydroponically grown lettuce.

Hydroponic farm as a business project
SMUTNÁ, Marta
The aim of this thesis is to verify the economic efficiency and environmental impacts of the practical application of bioeconomics in the form of a business project for the hydroponic farm built by an educational institution. The project plan evaluates the economic efficiency of the alternative method of plant cultivation. The economic analysis is followed by an evaluation of the environmental impacts of hydroponic cultivation. The first chapters of the thesis focus on the theory of bioeconomics, hydroponic cultivation and a description of current world megatrends. The thesis also discusses the role of hydroponics in the context of global challenges and the European Union´s view on hydroponics. It is followed by a chapter describing the methodology for proceeding with the development of a business plan and a cost-benefit analysis methodology. These methodologies provide guidelines for the practical part. The first part of the practical part of this thesis focuses on the business plan for the hydroponic farm project, which includes several subchapters and analyses. First, the characteristics of the owner, project and products are described, followed by analyses of the market, customers, competitors and suppliers, then the staffing, marketing strategy are described and the project implementation schedule is presented. All costs and revenues are quantified in detail in the individual chapters and from these, a financial plan is summarized, including financial statements and projections for various scenarios and options for financing the project. Subsequently, the economic management of the project and its potential success is evaluated using evaluation indicators, risk analysis, PESTEL, Porter's analysis of 5 competitive forces and SWOT analysis. The hydroponic project is then compared with the conventional agriculture production within the cost-benefit analysis and evaluated from an environmental perspective in association with theoretical knowledge and information.
