Abstract
The light intensity in a greenhouse covered with twin walled PMMA (steggdobbeltplatte of acryl) shows periodical variations as compared to the light intensity in a greenhouse covered with single glass.
The light intensity in the twin walled greenhouse is 20 percent higher in the morning hours but 25 percent lower in the afternoon, as compared to a greenhouse covered with single glass.
