The study was carried out in the doctoral thesis entitled, Research on the production of seedlings and flowers cut by gerbera in various variants of hydroponic cultivation, and refers to the identification of the best way to obtain as many flowers per plant as well as recommendation of the best type of substrate for obtaining cut flowers. In the study we used three varieties of gerbera, 'Dune’, 'Balance’ and 'Blind Date’’. The substrate variants used in the experiments were: V1 - peat with a pH of 4; V2 - Perlite; V3 - 50% Perlite + 50% peat with pH-4; V4 - 50% Perlite + 50% peat with pH 5.5; and V5 - Peat with pH 5.5 (Control Variant). We followed the response of plants grown in different types of substrate on the growth, development and yield of gerbera flowers in the unconventional system. Analyzes and correlations were performed with environmental factors to determine their influence on the number of flowers and their quality.
