Experiments were accomplished in the experimental field of the Faculty of Agricultural Engineering at State University of Campinas (Unicamp). Four varieties of strawberry were tested (Campinas, Seascape, Sweet Charlie and Tudla) 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 skin) in three greenhouses with different technical: i) greenhouse without air evaporative cooling nor CO2 aerial injection, ii) greenhouse with CO2 aerial injection and without air evaporative cooling and iii) greenhouse with CO2 aerial injection and air evaporative cooling. The productivity in grams per plant (P) and the number of fruits per plant (NF) were analyzed. The variety Campinas was better than the others. The best hydroponics system was the 150mm channel with a vase containing coconut fiber.
