Analyses were made in the experimental field of the Agricultural Engineering College at State University of Campinas (Unicamp). Four varieties of strawberry [Fragaria x ananassa (Weston) Duchesne ex Rozier] were tested in four hydroponics production systems (100mm and 150mm channels and 150mm channel with a vase containing coconut fiber and a vertical pipe containing carbonized rice rusk). Three greenhouses were tested: i) a greenhouse without air evaporative cooling nor CO2 aerial injection, ii) a greenhouse with CO2 aerial injection and without air evaporative cooling and iii) a greenhouse with CO2 aerial injection and air evaporative cooling. It was analyzed the leaf fresh (MFF) and dry mass in gram (MSF) and the leaf area in mm² (AF). The best hydroponics system was 150mm channel with a vase containing coconut fiber. The best environment condition was the one with air evaporative cooling and aerial injection of CO2.
