Samantha Ruth Prabhu once shared her simple hack for growing cabbage microgreens at home, saying all you need is a tray, cocopeat, seeds, water and a cool spot near a window. Microgreens are young edible greens that can be harvested within days. They are nutrient-dense, require little space and can be grown indoors. Beginners can fill a tray with cocopeat, sprinkle seeds, keep it moist, cover it for four days, then uncover and water daily. Samantha said they can be harvested from day eight.
