Method and device for crop cultivation

Abstract

The present invention relates to a device in which a crop is grown in an environment essentially free of daylight, whereby the crop in a climate-conditioned (10) growing space is exposed to bright artificial light from a group of artificial light sources (30) located in the growing space. During the growing cycle, the energy output from the artificial light sources (30) is prepared to absorb energy from the portion of the crop (50) illuminated by them, so that the crop near each group of artificial light sources is not subjected to a vapor deficit that is essentially constant and mutually equal.
