How to Ensure a Steady Supply of Microgreens


In the realm of healthy and vibrant nutrition, microgreens have rapidly emerged as the stars of the show. These tiny, nutrient-packed plants not only add a burst of flavor and color to your dishes but also pack a nutritional punch that can rival their full-grown counterparts.

Whether you’re a home cook looking to elevate your culinary creations or a health-conscious individual seeking to boost your daily nutrient intake, the question often arises: How do you get a constant supply of microgreens? In this comprehensive guide, we’ll delve into the world of microgreen cultivation, exploring various methods and tips to ensure a steady and sustainable supply.

Understanding the Microgreen Phenomenon

Microgreens are essentially young and tender seedlings of vegetables and herbs. They are harvested at an early stage, typically when the first true leaves (cotyledons) appear. Despite their small size, microgreens are rich in essential nutrients, including vitamins, minerals and antioxidants. They offer a unique flavor profile and are commonly used in salads, sandwiches, soups, and as garnishes.

The popularity of microgreens has skyrocketed in recent years due to their numerous health benefits and culinary versatility. However, their perishable nature often raises concerns about maintaining a constant supply. Let’s explore the strategies that can help you enjoy a continuous bounty of these nutritional powerhouses.

Cultivating Microgreens at Home

1. Choose the Right Microgreen Varieties

To establish a constant supply of microgreens, start by selecting the right varieties. Popular choices include basil, arugula, kale, radish and sunflower. Different microgreens have varying growth rates and flavors, so consider your preferences and available space when making your selections.

2. Gather Supplies

Gathering the necessary microgreen supplies is crucial for successful microgreen cultivation. You’ll need containers or trays, potting mix or soil, seeds, water, and light sources. Microgreens can be grown indoors or outdoors, depending on your climate and available space.

3. Sow Seeds Properly

Sow the seeds evenly in the prepared soil or growing medium. It’s essential to follow the recommended seeding density for each type of microgreen to ensure healthy growth. Lightly press the seeds into the soil, so they make good contact.

4. Provide Adequate Light

Microgreens require ample light to thrive. If you’re growing them indoors, place them near a sunny window or use artificial grow lights. Ensure they receive around 12-16 hours of light daily to promote robust growth and vibrant color.

5. Maintain Proper Humidity and Temperature

Maintaining the right levels of humidity and temperature is vital for microgreens. Covering your trays with a clear plastic lid or plastic wrap can help create a mini-greenhouse effect, ensuring the necessary moisture and warmth.

6. Regularly Water and Ventilate

Keep the growing medium consistently moist by watering gently. Be cautious not to overwater, as it can lead to mold growth. Additionally, allow for proper ventilation to prevent issues like damping, a common fungal problem.

7. Harvest at the Right Time

Microgreens are ready for harvest when they have developed their first true leaves, typically within 7-21 days, depending on the variety. Use clean scissors or shears to snip them just above the soil level. Harvesting at the correct stage ensures the best flavor and nutritional value.

8. Replant for Continual Harvest

To maintain a constant supply, replant new trays of microgreens every few days or weeks, depending on your consumption. This staggered planting approach ensures a steady rotation of mature microgreens ready for harvest.

Exploring Hydroponic and Aeroponic Systems

1. Hydroponic Cultivation

Hydroponics is a soilless growing method that allows you to cultivate microgreens with precision. In a hydroponic system, plants receive their nutrients from a nutrient-rich water solution. This method offers several advantages for ensuring a constant supply of microgreens:

  • Faster Growth: Hydroponically grown microgreens often mature more quickly than those grown in soil, allowing for a more frequent harvest.
  • Consistent Nutrient Delivery: With precise control over nutrient levels, you can ensure that your microgreens receive optimal nutrition throughout their growth cycle.
  • Space Efficiency: Hydroponic systems are compact and can be set up indoors, making them ideal for urban gardening or limited space.
  • Year-Round Cultivation: Hydroponics allows you to grow microgreens year-round, regardless of outdoor weather conditions.

2. Aeroponic Systems

Aeroponics is another soilless method that suspends plant roots in an air or mist environment. While it is less commonly used for microgreens than hydroponics, it can still be an effective way to ensure a constant supply:

  • Maximum Oxygenation: Aeroponic systems provide ample oxygen to plant roots, promoting rapid growth.
  • Water Efficiency: This method uses less water compared to traditional soil-based cultivation.
  • Reduced Disease Risk: With no soil to harbor pathogens, aeroponically grown microgreens are less susceptible to diseases.
  • Consistent Growth: Like hydroponics, aeroponics allows for precise control over nutrient delivery, ensuring consistent growth and quality.

Utilizing Vertical Farming

Vertical farming is an innovative technique that maximizes space utilization by stacking growing trays or shelves vertically. It’s an ideal option for urban dwellers or those with limited gardening space. Here’s how you can leverage vertical farming for a continuous supply of microgreens:

1. Choose the Right Setup

Select a vertical farming system that suits your available space and needs. Options range from simple shelving units with grow lights to more advanced hydroponic or aeroponic towers.

2. Optimize Lighting

Ensure that each level of your vertical farm receives adequate light. LED grow lights are energy-efficient and can be adjusted to provide the right spectrum and intensity for microgreen growth.

3. Rotate Crops

Plan your planting schedule to have multiple trays or shelves at different growth stages. This way, you can harvest from one tray while the others continue to grow, ensuring a constant supply.

4. Monitor Environmental Conditions

Regularly check and maintain the environmental conditions in your vertical farm, including temperature, humidity, and nutrient levels. Automated systems can help streamline this process.

5. Experiment with Varieties

Utilize the vertical space to experiment with various microgreen varieties. This not only adds diversity to your supply but also allows you to discover new flavors and textures.

Collaborating with Local Microgreen Suppliers

If cultivating microgreens at home or through advanced systems isn’t feasible for you, consider collaborating with local microgreen suppliers. Many urban areas now boast microgreen farms and businesses that can provide you with a consistent source of fresh microgreens. Here’s how to go about it:

1. Research Local Suppliers

Search online or ask for recommendations to identify microgreen suppliers in your area. Consider visiting farmers’ markets or specialty grocery stores that may carry locally grown microgreens.

2. Contact Suppliers

Reach out to potential suppliers to inquire about their product offerings, pricing, and delivery options. Some suppliers may offer subscription services that guarantee regular deliveries.

3. Quality Assessment

Request samples or visit the supplier’s facility to assess the quality and freshness of their microgreens. It’s essential to ensure that the product meets your standards.

4. Subscription or Standing Order

Many suppliers are willing to set up standing orders or subscriptions for their customers. This arrangement ensures a regular supply of microgreens without the hassle of constant reordering.

5. Support Local Businesses

By choosing local microgreen suppliers, you not only secure a steady supply but also support small-scale, sustainable agriculture in your community.
