Microgreens are young, edible seedlings grown for fresh flavor, color, nutrition, and quick indoor harvests. This category brings together Hatchi’s microgreen guides for readers who want practical tray-growing advice without unnecessary complication. Articles here cover seed selection, germination, blackout periods, watering, light, airflow, growing media, harvest timing, mold prevention, and crop-by-crop differences. Microgreens are useful for beginners because many crops can be grown in small spaces with simple equipment, yet they also reward careful technique as growers improve density, timing, and consistency. Radish, broccoli, mustard, kale, sunflower, pea shoots, and other crops each behave differently, so good results come from matching the seed to the right method. Use this page to learn how microgreens grow, why trays sometimes fail, and how to produce cleaner, stronger, better-tasting harvests from seed to cutting. Start with the main guides, then move into specific crops and methods.
