In an air conditioning cooled greenhouse substantial lower temperatures can be realized than in pad&fan greenhouses. However, growing at lower temperatures is more expensive in terms of electricity consumption for cooling. Therefore, growing at lower temperatures need to provide clear benefits in terms improved production or quality. In order to study this trade off, two of the High-tech compartments have been planted with various types of sweet pepper. The growing strategy (side shoot pruning, irrigation, CO2 dosing, screening and dehumidification) was equal for both compartments, but the temperature in H3 was on average 2 degrees below the temperature in H1, which was operated as usual. Usual means here that the temperatures were similar to the pepper growing cycles in previous years in Estidamah.
