What Are Microgreens and Why Grow Them?
Microgreens are young vegetable greens harvested just after sprouting. They pack intense flavor and concentrated nutrients, making them ideal for home gardeners seeking fresh, organic produce. Studies from the USDA show certain microgreens contain up to 40 times more nutrients than mature leaves, including vitamins C, E, and K.
Choosing the Right Seeds for Microgreens
Start with licensed seed suppliers to ensure quality. Popular varieties include broccoli, radish, and sunflower, each offering distinct tastes and growth rates. "Avoid using garden soil seeds," advises organic farming expert Jane Doe, "as microgreens require pathogens-free media."
Setting Up Your Microgreen Growing System
Use shallow trays (1-2 inches deep) with drainage holes. Fill with "soilless" seedling mix or coconut coir for optimal water retention. Pre-moisten the medium before seeding densely and covering lightly.
Lighting and Watering for Success
LED grow lights on a 12-16 hour timer boost growth when natural light is limited. Bottom watering—submerging trays briefly—prevents mold. Maintain 60-70°F temperatures; central heating zones work well indoors.
Harvesting and Storing Microgreens
Cut greens 1-3 inches tall with sterile shears. Store in airtight containers lined with paper towels for 5-7 day refrigeration. Incorporate into smoothies, salads, or garnishes for maximum nutritional benefits.
Troubleshooting Common Issues
Yellowing suggests poor drainage; powdery mildew results from overcrowding. Rotate fresh batches weekly to prevent pests like fungus gnats. Use food-grade hydrogen peroxide diluted 1:4 to treat mold spots.
Expanding Your Microgreen Garden
Stackable vertical trays optimize small spaces. For organic growers, compostable coconut husk trays reduce plastic waste. Experiment with mixed seed trays for "microherbs" combinations in gourmet cooking.
