Microgreens are nutrient-packed greens used in all types of dishes, including salads, smoothies, pastas, sandwiches, juices and more. They are hearty enough to stand on their own in a simple mixed green salad with a light dressing. Or you can brighten up your morning by adding them to your favorite smoothie. The most common micro greens include arugula, beet, broccoli, cabbage, carrot, chard, mustard and kale. Beginner Hydroponics
