Introduction Many countries rely heavily on mustards as a staple food in their diet. Tis is because the seed contains many poly• phenolic compounds, including vitamins A, C, and E, cal• cium,andiron[1,2].Additionally,theyprovideanimportant source of dietary antioxidants and have high radical scav• engingactivityinpreventingvariouschronicdiseasessuchas cancerandcardiovasculardisease[3,4].BasedontheCentral BureauofStatistics[5],mustardproductioninIndonesiawill reach approximately 667 thousand tons in 2020.

However,thecountry’sgrowingpopulationhasresulted in land conversion issues, directly narrowing agricultural land[6–8].Tenarrowertheland,thelowerthehorticulture productivity.Temainmilestoneasapromisingsolutionto overcomingthisissueisapplyingthehydroponictechnique. Tis is a cultivation technique using water or nutrient so• lution as a growing medium, known as soilless culture [9]. Te main advantages are [10]as follows: (1) possible use of areas unsuitable for conventional agriculture, such as dry and degraded land; (2) plant independence for weather conditions;(3)year•roundcultivation;and(4)reducingthe use of labor•intensive activities such as weeding and soil preparation. Te activity in hydroponics is also arguably lighter than conventional farming [11, 12].
