The theoretical part of diploma thesis briefly focuses on botanical characteristics of cannabis, legislation of cannabis cultivation in Czech republic, agrotechnics and harvest of hemp. The cultivation technologies used in production and harvest of cannabis for pharmaceutical purposes are described in more details. In the practical part was established an experiment with cannabis plants. This experiment was carried in laboratory at department of plant biology at Mendel university in Brno. The experiment was carried out in two variants of light spectrum (white LED lights emitting complete visible spectrum and combination of blue and red LED in ratio 1:1), which were dividen into three groups with different trim method. In plants were observed parameters of quantum yield of electron transport of photosystem II, chlorophyll fluorescence, yield of dried flowers and selected secondary metabolites. In each of lighting and trim variants have been recorded various results. As results shown, white LED lights emitting a full visible spectrum appear to be more effective than the blue and red spectrum in ratio of 1:1. Effect of trimming in this experiment was not statistically conclusive.
