Design of a mechanism for adaptive distribution of plants in hydroponic cultivation
 Lupínek, Antonín ; Lošák, Pavel (referee) ; Naď, Martin (advisor)
This thesis addresses the issue of energy consumption n the field of increasingly popular hydroponic cultivation technology and its possible reduction with the help of movement mechanism. The mechanism in question adjusts the distances between plants in order to reduce the number of active artificial lights at different stages of plant growth. In order to achieve this goal, several movement mechanisms were proposed using the theoretical knowledge obtained in the first part of the thesis, from which a mechanism for the movement of the traverses with the plants along the channel of the NFT system, realized with the help of an electric motor and a set of pulleys, was subsequently selected. This mechanism was subsequently modelled in detail and used for the development of the motion study.

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.
