This study was conducted to determine the effect of air anions on lettuce growth in a plant factory. Red leaf lettuce (Lactuca sativa L. cv. ‘Jeokchima’) seedlings grown under normal growth conditions (20°C, fluorescent lamp, 150 ± 3 μmol·m−2·s−1 PPFD, 12-h photoperiod) for 18 days were transplanted to hydroponic systems in a plant factory equipped with(More)
Air anions affect plant growth by stimulating various biological mechanisms. We investigated the effect of atmospheric anion concentrations on plant growth and mineral concentration in kale (Brassica oleracea var. acephala cv. TBC) plants cultivated in a plant factory. Kale seedlings grown under normal growth conditions for two weeks were transplanted to a(More)
