The marketable sensory characteristics (crispness, sweetness, shape, and
color) of fresh plants were also evaluated. Plants were hydroponically cultured with a 16-h photoperiod
at 24/20 ◦C (day/night), 75% relative humidity, 900 mol mol−1 CO2 level, and 210 mol m−2 s−1 photon
flux density under RB LED, RB and white (RBW) LED, and a fluorescent lamp (FL, as a control) inside
growth chambers for 20 days (15 days after sowing).
