| Abstract:
A greenhouse computer model and commercial production data for rose production were studied for the Netherlands at 52°N latitude and Ohio at 41°N latitude. The average winter yields were similar even though the winter solar radiation in Ohio was about 2.5 times greater than that in the Netherlands. In the spring, the average monthly solar radiation for the Netherlands was equal to the previous monthly average for Ohio. The Ohio winters were 5°C colder and summers were 5°C warmer than the Netherlands. The temperature variation and solar radiation was much greater for Ohio than for the Netherlands. The heat requirement for Ohio was 20–30 percent higher than the Netherlands in the winter and 15–40 percent lower in the spring and fall. The total annual heat requirement was almost the same for both locations for the same heating system efficiency. | |
