Create an optimal climate with the right ventilation system

An optimal crop yield starts with creating the right greenhouse climate. A durable precision ventilation system in combination with a movable screening system is an essential success factor for perfect climate conditioning. Ventilation allows you to keep heat both inside or outside, and to maintain the desired relative humidity level. Depending on your cultivation strategy, specific and precision window settings can be used to ventilate and uniformly and hermetically close your greenhouse.
