Microgreens are tiny, nutrient-packed seedlings harvested just days after germination. They’re quick to grow, take up minimal space, and are perfect for beginners—especially if you want fresh greens year-round indoors.
In this guide, you’ll learn how to grow your own microgreens at home, from seed to harvest, in less than two weeks.
1. What Are Microgreens?
Microgreens are young vegetable or herb plants, harvested when the first true leaves appear.
Common Microgreens:
- Radish
- Broccoli
- Sunflower
- Pea shoots
- Kale
- Arugula
- Beets
- Basil
They’re not sprouts or baby greens—they fall in between, offering flavor, texture, and nutrition.
2. Why Grow Microgreens Indoors?
Benefits:
- Fast growth—ready in 7–14 days
- Packed with vitamins and antioxidants
- Great for small spaces and apartments
- Requires no outdoor space
- Perfect for year-round harvests
They’re ideal for health-conscious gardeners or culinary enthusiasts.
3. Supplies You’ll Need
- Shallow trays or containers (with drainage holes preferred)
- Seed starting mix or coconut coir
- High-quality microgreen seeds
- Spray bottle
- LED grow light (or sunny windowsill)
- Scissors or sharp knife for harvesting
Optional: humidity dome or plastic wrap to help with germination.
4. Step-by-Step: How to Grow Microgreens Indoors
Step 1: Choose Your Seeds
Look for certified organic microgreen seeds from trusted sources. Mix seed varieties for a custom blend.
Step 2: Prepare the Growing Tray
- Fill your tray with 1–2 inches of moist, fine-textured growing medium
- Level the surface gently with your hand
Step 3: Sow the Seeds
- Sprinkle seeds densely but evenly over the surface
- Gently press seeds into the soil
- Mist with water and cover with a humidity dome or tray lid
Step 4: Germination
- Keep trays in a dark, warm place (65–75°F / 18–24°C) for 2–4 days
- Mist daily to maintain moisture
- Remove cover once seeds sprout
Step 5: Add Light
- Move trays under LED grow lights or into a bright window
- Provide 12–16 hours of light daily
- Water gently from the base or with a spray bottle
5. Best Microgreens to Start With
- Radish: Fastest to harvest (6–8 days)
- Broccoli: Mild flavor and very nutritious
- Sunflower: Crunchy with a nutty taste
- Pea Shoots: Sweet and tender
- Mustard or Arugula: Spicy and bold
Experiment to find your favorite flavors.
6. Harvesting Microgreens
- Harvest when first true leaves appear
- Use clean scissors to cut just above the soil line
- Rinse and pat dry before storing
Microgreens can be stored in the fridge for up to 5–7 days in an airtight container.
7. Troubleshooting Common Issues
Problem: Mold
- Improve airflow
- Avoid overwatering
- Use cinnamon as a natural antifungal
Problem: Uneven Growth
- Use a seed spreader or sieve
- Provide even light exposure
- Keep growing surface level
Problem: Weak or Leggy Sprouts
- Increase light intensity
- Ensure trays aren’t too warm during growth
8. Can You Regrow Microgreens?
In most cases, no—microgreens are one-time harvests. After cutting, compost the used soil and replant with fresh seeds for your next crop.
Conclusion: Fresh Greens, Anytime, Anywhere
Microgreens are one of the simplest, fastest ways to enjoy gardening indoors. With just a tray, some seeds, and a little light, you can grow a nutrient-rich garden on your kitchen counter or windowsill—all year long.
Start today and enjoy your first harvest in under two weeks.
