The effect of different growing media: peat and mixtures of peat and granulated, water repellent rockwool, 3:1 and 1:1, on growth of cyclamen (2 varieties) and poinsettia (3 varieties) was evaluated during two consecutive autumns. Poinsettia were grown as pinched or non-pinched plants. All plants were grown on ebb-and-flow benches and fertigated in each irrigation with nutrient solution based on complete fertilizers Peters 15:11:29 for cyclamen and Peters 15:5:25 for poinsettia. EC of nutrient solution for cyclamen was 1.2 and for poinsettia 1.8 mS/cm. Growth parameters of cyclamen were evaluated at full flowering and of poinsettia when the bracts were fully colored
