Tiny but Mighty: The Health and Environmental Benefits of Microgreens

Microgreens, also called baby greens, are young vegetables, grains, or herbs harvested at an immature growth state before or shortly after developing their cotyledonary or embryo leaves. Both microgreens and sprouts are extensively used in vegan gourmet restaurants to enhance meals, but they differ in characteristics, growth stages, harvest times, flavors, and textures. Classified as superfoods, these plants are rich in minerals, vitamins, and antioxidants that counteract harmful free radicals. Scientific studies have also confirmed their anticancer, antibacterial, anti-inflammatory, anti-obesity, and anti-diabetic properties. These studies highlight that most microgreens are richer in nutrition than their adult counterparts. One study found that broccoli microgreens inhibited the growth of numerous bacteria, including Staphylococcus aureus, which can cause skin infections, pneumonia, and heart valve infections.

The hydroponic growth of microgreens is mainly used for commercial ends, while smaller quantities are cultivated by individuals through use of a growth medium. When planting your microgreens, remember that the growing medium needs to be in a sanitized, hygienic state, free from any bacterial, viral, or pest populations, so it’s important to buy a high-quality product. Most microgreens grow best in temperatures between 15 to 24 degrees Celsius. Using a dehumidifier can help maintain the humidity at around 50%. Microgreens show promise for sustainable food production in climate-vulnerable regions as they need less water than the average food crop. Cultivating microgreens in urban areas could be an excellent way to mitigate global warming. Radishes, broccoli, arugula, kale, beets, sunflowers, peas, basil, cilantro, and mustard greens are some of the 30 varieties of microgreens or superfoods that may be grown in small containers, require minimal care, and are ready to harvest within 7-21 days. Whenever possible, use organic seeds. Monitor the microgreens as they grow to ensure they get enough water, light, and nutrients.
