The young plants of three cultivars of green pepper were subjected to four lighting systems: (1) natural lighting, (2) 75 μmol m−2 s−1 of supplementary lighting (HPS lamps) for a photoperiod of 16 h, (3) 125 μmol m−2 s−1 of supplementary lighting for 16 h, and (4) 125 μmol m−2 s−1 of supplementary lighting for 20 h. Two growing media were also compared, rockwool and a peat moss medium. The use of supplementary artificial lighting substantially increased the specific weight before and after drying, the percentage of dry matter, early, commercial and total yields, the total number of fruits harvested and the average weight of commercial fruits. Compared to the 75 μmol m−2 s−1 treatment, the two 125 μmol m−2 s−1 treatments resulted in increases in all parameters studied. The use of supplementary lighting of 125 μmol m−2 s−1 for 20 h, compared with 16 h, significantly increased only the productivity of the young plants and the total number of fruits harvested. The young plants subjected to supplementary light...
