Improving light use efficiency of cucumber in a plant factory setting

This study investigated whether lower light intensity could be compensated for by higher CO2 concentration. Two compartments were compared: the reference with 260 μmol/m2/s & 600 ppm CO2, and the treatment compartment with229 μmol/m2/s and 1400 ppm CO2. Cucumber (Cucumis sativus L.) was grown for 112 days at plant densities of 2.89plants/m2 and 2.22 plants/m2 D/N temperature of 22.5/21 and relative humidity D/N of 80/93% for both compartments.Yield (kg/m2) was significantly higher (
