Why Grow Microgreens at Home?

Fast Results: Most microgreens are ready to harvest within 1–3 weeks.
Easy to Grow: They require minimal space, time, and effort.
Highly Nutritious: Packed with vitamins, minerals, and antioxidants.
Cost-Effective: Growing your own microgreens is cheaper than buying them at the store.
Culinary Versatility: Add them to salads, sandwiches, smoothies, and more.

Materials Needed to Grow Microgreens

Seeds: Choose high-quality seeds labeled for microgreens.
Growing Tray: A shallow tray or container with or without drainage holes.
Growing Medium: Options include potting soil, coconut coir, or hydroponic mats.
Spray Bottle: For watering the seeds and maintaining moisture.
Light Source: Natural sunlight or grow lights.

Step-by-Step Instructions for Growing Microgreens

Step 1: Prepare the Tray

Fill a shallow tray with 1–2 inches of growing medium. Moisten the medium evenly, but avoid overwatering.

Step 2: Sow the Seeds

Sprinkle the seeds evenly across the surface of the growing medium. Press them gently into the surface but do not bury them.

Step 3: Mist and Cover

Mist the seeds lightly with water using a spray bottle. Cover the tray with a lid or plastic wrap to create a humid environment.

Step 4: Monitor Germination

Place the covered tray in a warm, dark spot. Check daily and mist as needed to keep the medium moist. Remove the cover once the seeds sprout, usually within 2–3 days.

Step 5: Provide Light

Move the tray to a sunny location or place it under grow lights. Microgreens require 12–16 hours of light daily for healthy growth.

Step 6: Water Regularly

Mist or water lightly to keep the growing medium consistently moist but not soggy.

Caring for Microgreens

Consistent Moisture: Ensure the growing medium stays evenly moist.
Adequate Light: Rotate the tray daily for even light exposure.
Air Circulation: Good airflow prevents mold and promotes healthy growth.

Harvesting Microgreens

When to Harvest:

Microgreens are ready when they are 1–3 inches tall and have developed their first set of true leaves, typically 7–21 days after planting.

How to Harvest:

Use clean scissors to cut the greens just above the soil line.

Storing Microgreens:

Place harvested microgreens in an airtight container and store them in the refrigerator for up to a week.

Common Problems and Solutions

1. Mold Growth:

Problem: Excess moisture or poor ventilation.
Solution: Reduce watering and ensure proper air circulation.

2. Leggy Microgreens:
