Arugula microgreens, or rocket, are types of microgreens with a unique peppery taste. It is also one of the most popular types of microgreens for the salad mix and garnishing. Arugula is fairly easy to grow and germinate quickly within just a couple of days.
While you are growing them on the tray, 10″ by 20″ in my case, you have to make sure you spread the seed evenly over the growing tray and don’t overwater it. Unlike the others, arugula prefers a minimum moisture environment to grow better.
