Abstract The indoor climate, the heat use and the production of a demonstration trial with sweet pepper are compared with a commercial grower. With intensive use of the screens a 59% lower use of heat is achieved. The intensive use of screens has decreased the amount of light with 4% in comparison to the commercial grower. The biggest difference was during the first three (winter) months of cultivation. The roof also showed 4% less light transmission. By dosing 64% less CO2, a lower CO2 concentration was obtained, which should have led to 4% less photosynthesis according to the CO2-rule of thumb. Despite the lower light intensity and lower CO2 concentration, the production was just 10% lower than at the commercial grower. This indicates that CO2 and light have been a little less restrictive than what would be expected from the rules of thumb.
