“With an eye toward creating food for people with certain health conditions, scientists in Italy grew radish, pea, arugula, and Swiss chard plants, precisely controlling certain nutrients. And they did it without any soil.

Working at a commercial microgreen farm in southern Italy, researchers wanted to see if they could tailor the amount of iodine and potassium in a range of vegetables. The greens at this farm are grown in a liquid medium which, the researchers say, made the project easier to undertake.”
