What Are Microgreens and Why Grow Them?
Microgreens are young, tender greens harvested just after their first true leaves appear, typically 7-21 days after germination. Unlike sprouts, which are grown in water and eaten whole including roots and seeds, microgreens are grown in soil or growing medium and harvested by cutting the stems just above the soil line.
These miniature vegetables and herbs offer concentrated nutrition that far exceeds their mature counterparts. Research shows that microgreens can contain 4-40 times higher vitamin and antioxidant concentrations than adult plants, making them nutritional powerhouses in tiny packages. Popular varieties include broccoli, radish, kale, arugula, peas, sunflower, and cilantro, each offering unique flavors and health benefits.
The appeal of growing microgreens extends beyond nutrition. They require minimal space, grow quickly, and can be produced year-round indoors, making them ideal for urban farming, seasonal growing, and continuous harvest systems. Their delicate textures and intense flavors make them popular additions to salads, sandwiches, smoothies, and gourmet dishes.
Essential Supplies: Simple Tools for Success
Growing microgreens requires surprisingly few materials, most of which you may already have at home. The basic setup can be assembled for less than $20 and will produce multiple harvests.
Required Materials:
- Growing Trays: Two shallow trays (one with drainage holes, one solid) or repurposed containers like takeout containers or pie tins
- Growing Medium: Organic seed starting mix, coconut coir, or specialized growing mats
- Seeds: High-quality microgreen seeds or regular vegetable seeds
- Water Source: Spray bottle or small watering can
- Light: Sunny windowsill or basic LED grow light
Optional but Helpful:
- Humidity Dome or Cover: Plastic wrap, clear container lid, or specialized dome
- Sharp Scissors: For clean harvesting
- Measuring Tools: To ensure proper seeding density
The beauty of this setup is its scalability. Start with a single tray to learn the basics, then expand your operation as your confidence and appetite for fresh microgreens grows.
Step-by-Step Growing Process
Step 1: Prepare Your Growing Space
Choose a location that receives 4-6 hours of indirect sunlight daily, such as a south-facing windowsill. Clean and sanitize all equipment with hot, soapy water to prevent contamination. Set up your workspace with easy access to water and good ventilation to prevent mold issues.
Step 2: Prepare the Growing Medium
Fill your drainage tray with 1-2 inches of moist growing medium. The soil should be evenly damp but not waterlogged. Level the surface by gently tamping it down with a flat object, creating a smooth, firm seedbed that promotes even germination.
Step 3: Seed Preparation and Sowing
Some larger seeds like peas, sunflowers, and cilantro benefit from 4-8 hours of pre-soaking to accelerate germination. After soaking, drain and rinse the seeds until water runs clear. Spread seeds evenly across the soil surface, creating a dense but not overlapping layer. Most microgreens require approximately 1-2 tablespoons of seeds per standard tray.
Step 4: Initial Germination Period
Cover the seeded tray with a humidity dome, plastic wrap, or another tray to create a dark, humid environment that encourages germination. Place the covered tray in your growing location and maintain temperatures between 65-75°F (18-24°C) for optimal sprouting.
Growing Requirements and Timeline
| Growth Stage | Duration | Light Requirements | Watering Needs | Key Activities |
|---|---|---|---|---|
| Germination | Days 1-3 | Dark environment | Mist 1-2 times daily | Keep covered, maintain moisture |
| Early Growth | Days 4-7 | Bright indirect light | Bottom watering daily | Remove cover, provide light |
| Development | Days 8-14 | 4-6 hours direct light | Water as needed | Monitor growth, prevent mold |
| Harvest Ready | Days 7-21 | Continued light exposure | Maintain moisture | Harvest when 2-3 inches tall |
Watering Techniques for Healthy Growth
Proper watering is crucial for microgreen success and the most common source of beginner challenges. During germination, use a fine mist spray bottle to keep seeds moist without disturbing their placement. The growing medium should remain consistently damp but never waterlogged.
Once seedlings emerge and develop their first true leaves, transition to bottom watering by adding water to the solid tray beneath your drainage tray. This method prevents water from sitting on delicate leaves while ensuring roots receive adequate moisture. Monitor daily and water when the growing medium feels dry to the touch.
Watering Best Practices:
- Use room temperature, clean water
- Avoid overhead watering on mature microgreens
- Maintain consistent moisture without creating standing water
- Ensure proper drainage to prevent root rot
- Watch for signs of overwatering (yellowing, mold) or underwatering (wilting, stunted growth)
Light Requirements and Optimization
Microgreens need adequate light to develop properly and achieve their characteristic colors and flavors. Natural sunlight from a south-facing window providing 4-6 hours of direct light works well for most varieties. However, leggy, pale growth indicates insufficient light exposure.
For year-round production or limited natural light situations, LED grow lights provide an excellent solution. Position lights 3-5 inches above the microgreens and run them for 12-16 hours daily. Even basic LED shop lights can effectively grow healthy microgreens when positioned properly.
Light Management Tips:
- Rotate trays regularly to ensure even growth
- Watch for light-seeking behavior (leaning toward light source)
- Adjust light distance based on plant response
- Provide consistent daily light exposure
- Consider seasonal adjustments for natural light variations

Common Problems and Solutions
Mold Growth: Usually appears as fuzzy white, gray, or black growth on soil or seedlings. Prevent by ensuring proper air circulation, avoiding overwatering, and maintaining clean growing conditions. Increase ventilation and reduce humidity if mold appears.
Poor Germination: Often caused by old seeds, incorrect moisture levels, or temperature issues. Use fresh, high-quality seeds, maintain consistent moisture, and ensure appropriate temperatures for your chosen varieties.
Leggy Growth: Indicates insufficient light. Move trays closer to light source or increase daily light exposure. Leggy microgreens are still edible but less desirable.
Damping Off: Soil-borne fungus that causes seedlings to collapse at soil level. Prevent by using sterile growing medium, avoiding overcrowding, and ensuring proper drainage.
Harvesting and Storage
Microgreens are ready to harvest when they reach 1-3 inches in height and have developed their first true leaves, typically 7-21 days after sowing depending on the variety. Use clean, sharp scissors to cut stems just above the soil line, harvesting only what you’ll use immediately for best flavor and nutrition.
Harvesting Tips:
- Cut early in the day when plants are most turgid
- Harvest just before use for maximum freshness
- Cut cleanly to avoid damaging remaining plants
- Rinse gently if necessary, but avoid washing unless required
- Store unharvested microgreens in refrigerator for up to one week
Nutritional Benefits and Culinary Uses
Microgreens offer exceptional nutritional density, containing concentrated vitamins, minerals, and antioxidants. Broccoli microgreens, for example, contain up to 40 times more sulforaphane than mature broccoli, a powerful compound with anti-cancer properties.
Culinary Applications:
