Beginner’s Guide to Microgreens at Home (No Grow Lights)
Microgreens are nutrient-dense, fast-growing plants harvested just after sprouting. They don’t require expensive equipment or grow lights — just a sunny windowsill, a tray, and a little patience. This editorial walks beginners through the process step by step.
Why microgreens?
Microgreens pack concentrated flavor and nutrition. They’re rich in vitamins A, C, and K, and add color and crunch to salads, sandwiches, and smoothies. Growing them at home saves money and ensures freshness.
Seeds to start with
- Radish Spicy, fast-growing, ready in 7 days.
- Broccoli Mild flavor, nutrient-rich, harvest in 10 days.
- Sunflower Crunchy texture, nutty taste, harvest in 12–14 days.
- Pea shoots Sweet flavor, tender stems, harvest in 10–14 days.
- Mustard Peppery kick, harvest in 7–10 days.
Supplies you’ll need
- Shallow tray or container with drainage holes
- Potting mix or coconut coir
- Spray bottle for misting
- Seeds (untreated, food-grade)
- Sunny windowsill or balcony
Step-by-step process
1. Prepare the tray
Fill the tray with 1–2 inches of potting mix. Level the surface and moisten lightly.
2. Sow the seeds
Scatter seeds evenly across the surface. Press gently into the soil but don’t bury deeply.
3. Cover and germinate
Cover the tray with a lid or another tray to create darkness. Mist daily until sprouts appear.
4. Move to light
Once sprouts emerge, place the tray on a sunny windowsill. Rotate daily for even growth.
5. Water carefully
Mist soil to keep it moist but not soggy. Avoid overwatering, which causes mold.
6. Harvest
Cut microgreens just above the soil line when the first true leaves appear. Rinse gently and enjoy fresh.
Common mistakes
- Overwatering: Leads to mold and root rot.
- Too little light: Causes leggy, pale sprouts.
- Dense seeding: Crowding reduces airflow and increases disease risk.
- Skipping rotation: Plants lean toward light and grow unevenly.
Tips for success
- Use untreated seeds labeled for sprouting.
- Keep trays in a bright, south-facing window.
- Harvest promptly to avoid bitterness.
- Experiment with blends for flavor variety.
- Clean trays thoroughly between plantings.

Styling ideas
Microgreens can be grown in decorative trays or jars, doubling as kitchen décor. Place trays on open shelving for a fresh, green accent. Harvested greens can be displayed in small bowls for easy snacking.
Microgreens prove that gardening doesn’t need grow lights or big spaces. A sunny window and a little care deliver fresh, nutritious greens in under two weeks.
