This work had as its major aim the hydroponic production of strawberries with the cooling of the nutrient solution, in Jaboticabal - SP - Brazil. The experiment was conducted in a covered greenhouse with a plastic film and seed transplantation achieved on January 9, 2002. Two varieties of strawberries were evaluated: Campinas and Sweet Charlie, both cultivated under the hydroponic system NFT type with or without cooling the nutrient solution. The cooling of the nutrient solution at about 12 °C was in a heating exchange device. The Sweet Charlie variety presented the best results for both the average weight and number of pseudofruit, longitudinal average diameter, cross average diameter, average number of pseudofruit and productivity. The cooling of the nutrient solution confered greater number of pseudofruit collected and better productivity of Sweet Charlie variety. However, the cooling of the nutrient solution didn't cause any effects over the Campinas variety.
