The Growing Process: From Seed to Harvest

The microgreen growing process is relatively simple, but attention to detail is crucial for success.

Step 1: Soaking Seeds (Optional)

Some seeds benefit from soaking in water for a few hours before planting. This helps to soften the seed coat and improve germination rates. Check the seed packet for specific soaking instructions.

Step 2: Planting Seeds

Fill your growing trays with your chosen growing medium. Moisten the medium thoroughly but avoid overwatering. Spread the seeds evenly over the surface of the medium. The seeding density will vary depending on the variety. Refer to seed packet instructions.

Step 3: Covering the Seeds

Cover the seeds with a thin layer of the growing medium or a humidity dome. This helps to keep the seeds moist and promote germination.

Step 4: Germination

Place the trays in a dark, warm location (around 20-24°C or 68-75°F). Mist the seeds regularly to keep them moist. Germination typically takes 1-3 days.

Step 5: Lighting

Once the seeds have germinated, remove the humidity dome and expose the seedlings to light. Position the grow lights a few inches above the trays. Adjust the height as the microgreens grow.

Step 6: Watering

Water the microgreens regularly, either by misting them from above or by bottom watering. Avoid overwatering, as this can lead to mold and disease. Bottom watering involves placing the growing tray in a tray of water and allowing the microgreens to absorb the water from below.

Step 7: Harvesting

Microgreens are typically harvested when they have developed their first true leaves (the leaves that appear after the cotyledons, or seed leaves). Use sharp scissors or a knife to cut the microgreens just above the growing medium. Gently wash the microgreens and dry them thoroughly before packaging.

Optimizing Your Growing Environment: Light, Temperature, and Humidity

Creating the right growing environment is essential for optimal microgreen growth. Consider these factors:

Light

Microgreens need ample light for photosynthesis. LED grow lights are the most efficient option, providing the full spectrum of light needed for growth. Adjust the intensity and duration of the light based on the specific needs of the variety.

Temperature

The ideal temperature for microgreen growth is between 18-24°C (64-75°F). Maintain a consistent temperature to promote uniform growth.

Humidity

High humidity (60-80%) is beneficial during germination. After germination, reduce the humidity to prevent mold and disease. Good air circulation is essential for reducing humidity.

Nutrient Solutions: Feeding Your Microgreens

While microgreens can grow without supplemental nutrients, adding a nutrient solution can enhance their growth and flavor, particularly in hydroponic setups. Here's a breakdown of key considerations:

Type of Nutrient Solution: Choose a balanced nutrient solution specifically formulated for microgreens. These solutions typically contain nitrogen, phosphorus, potassium, and micronutrients.
Concentration: Follow the manufacturer's instructions for the correct concentration. Over-fertilizing can harm the microgreens.
Application Method: Nutrient solutions can be applied by misting the microgreens or by adding them to the watering tray for bottom watering.
Organic Options: Organic nutrient solutions are available for growers who want to maintain organic certification.
