Abstract
Two similar greenhouse compartments, one covered with twin-wall PVC panels, the other with single layer glass, were compared with respect to heating energy usage, air relative humidity, light transmission and tomato productivity.
The PVC cover reduced heat loss to about 22% of that of the glass house.
Relative humidity was higher in the PVC house.
Light admitted in the PVC house was 18% less than in the glass house.
Seasonal yields were comparable under both glazing systems although early yields were delayed under PVC.
