Abstract
In a method and device for cultivating a crop, cultivation takes place in an at least a substantially daylight-free, climate-conditioned cultivation space. The cultivation space extends between a first side and an opposite second side, wherein the crop is exposed to photosynthetically active radiation from an array of spatially separated artificial light sources. An airflow is guided over the crop from the first side to the second side. The artificial light sources are spatially distributed over the crop. Downstream light sources of the array of light sources produce a higher dosage of photosynthetically active radiation than light sources located further upstream as seen in the flow direction of the airflow guided over the crop.
