In the present study, lettuce production under the dosed and open hydroponic systems was investigated. The tested substrates were perlite : peat (4 : 1, v/v), sand : peat (4 : 1, v/v) and sand: peat : perlite (3 : 1 : 1, v/v/v) under different shading treatments control, i.e. (without shading), medium shading (40 % shade) and heavy shading (80 % shade). The current study was conducted with lettuce (Laciuca saliva). The total yield was higher with the closed systems compared with open ones. Perlite and perlite + peat mixture gave the highest yields among the tested substrates. The highest nutrient consumptions were obtained from perlite and perlite + peat (4 : 1. v/v). On the other hand, medium shading (40 % shade) gave the highest yield Compared with other treatments. Also, the results obtained indicated that in the closed system could save both water and nutrient consumption.
