Ventilation of low plastic tunnels. Effect of the position of the perforations


Acta Horticulturae (42): 273-289
Ventilation of low plastic tunnels. Effect of the position of the perforations
An experiment is described on ventilating low plastic tunnels, using an early tomato crop of determinate habit. Very promising results were obtained from perforations on the ridge of the tunnels in comparison with perforations on the sides. At 30 cm from the ground the maximum air temperature in tunnels with ridge perforations was 2-4 deg C lower than in tunnels with side perforations: the minimum temperatures were the same in both treatments.
