Abstract Modern greenhouses are using, today, hydroponic systems with the latest technology. Temperature, ventilation and amount of fertilizer are computer controlled, the works in green and cucumbers harvesting are only manually operations performed. However, sometimes during the growing season on plants, acts, with depressive effects, some water sources insufficient controlled. So, in hydroponic greenhouse are some essential factors that contribute to the growth and plant development and is necessary to be constantly monitored. The paper presents the influence on the cucumber plants of the irrigation water quality, coming from deep drilling and from melted snow and collected in special tanks.
