The research were conducted in a plastichouse in Antalya, Turkey. The aim of research was to compare the effects of different support media (sphagnum peat , cocopeat, rockwool)  under a static hydroponic system on  growth  parameters such as length, width, weight , root length , root neck width , the number of leaf, root neck-shoot apex distance  in lettuce and salad cultivars (Bohemia, Bijou, Bitez, Nestorix). In this study, the best growth results were obtained from Bitez group plants cultivated in sphagnum peat media with mean values of 26.06 cm for plant length, 543.93 g for plant weight and 62.11for the number of  leaf per plant.  Lowest values were found in Nestorix group cultivated in cocopeat media with mean values of 13.56cm for plant length, 92.24g for plant weight and 23.33 for plant leaf number. The comparision of the organic and inorganic material based culture media showed that plants exhibit beter productivity results when cultured in organic material based media. Thus, sphagnum peat, an organic material based media is the most adequated to be used in hydroponic lettuce and salad culture.
