How to Grow Mixed Microgreens Indoors: A Beginner’s Guide to Bountiful Harvests

Growing mixed microgreens indoors is an enriching endeavor that not only enhances your culinary experiences but also provides an opportunity to engage with nature, regardless of where you live. These tiny plants are packed with flavor and nutrients, making them a perfect addition to salads, sandwiches, and smoothies. This beginner’s guide will walk you through all the steps necessary for growing a vibrant indoor microgreens garden.

What Are Microgreens?

Microgreens are young, edible plants that are harvested just after the first true leaves (cotyledons) appear. They are typically harvested within 7 to 21 days after planting, depending on the species. Microgreens are not only flavorful, but they’re also nutrient-dense, containing vitamins, minerals, and antioxidants that can enhance your overall health.

Why Grow Microgreens Indoors?

Growing microgreens indoors has several advantages:

1. Space Efficiency: Microgreens require minimal space, making them suitable for small apartments or homes.
2. Year-Round Growing: You can grow microgreens indoors regardless of the season or climate.
3. Flavor and Freshness: Freshly harvested microgreens offer unrivaled flavor compared to store-bought varieties.
4. Cost-Effective: Growing your own can save money, especially if you consume a lot of greens.

What You Need to Get Started

Supplies Required

1. Seeds: Choose a mix of seeds suited for microgreens. Popular options include kale, radish, mustard, and basil. Ensure the seeds are specifically marked for microgreen growth.
2. Growing Medium: A good-quality potting soil or seed-starting mix is essential. Avoid using regular garden soil, which may harbor pests and diseases.
3. Containers: Shallow trays or containers with drainage holes work best. You can use recycled containers, like plastic food trays, if they have holes for drainage.
4. Water: A spray bottle or watering can for gentle watering.
5. Light: Natural light or grow lights will be needed to provide adequate illumination.
6. Plastic Lid or Clear Plastic Wrap: To create a humid environment during germination.

Step-by-Step Instructions

Step 1: Select Your Seeds

Choose a mix of microgreen seeds based on your flavor preferences and nutritional goals. Some popular mixed varieties include:

• Spicy Mix: Combine radish, mustard, and arugula for a zesty flavor.
• Sweet Mix: Pair basil, beet, and sunflower seeds for a sweeter profile.
• Nutritious Mix: Blend kale, spinach, and broccoli for a nutrient-packed option.

Make sure to check that the seeds are non-GMO and free of pesticides.

Step 2: Prepare Your Growing Containers

Fill your containers with about 1-2 inches of moistened growing medium. Lightly pack the soil without compressing it too hard, as microgreens need good drainage and air circulation. After filling, use a spray bottle to moisten the soil evenly.

Step 3: Sow the Seeds

Scatter your selected seeds evenly across the surface of the soil. Aim to cover the soil with a uniform layer of seeds without overcrowding. The recommended density is about 1-2 seeds per square inch.

After sowing, lightly press down on the seeds to ensure good contact with the soil. You can sprinkle a thin layer of soil or vermiculite on top of the seeds if desired, but it’s not always necessary, especially with larger seeds.

Step 4: Watering

After sowing, mist the soil with water until it’s evenly moistened. Avoid soaking it completely, as this can lead to fungal issues. Cover your containers with a plastic lid or wrap to maintain humidity, which aids germination.

Step 5: Provide Light

Once the seeds germinate (which typically happens within 3-7 days), remove the cover and place your microgreens in a bright location. Aim for at least 12-16 hours of light per day. If natural light isn’t sufficient, consider using grow lights positioned a few inches above the plants.

Step 6: Watering and Care

Check the moisture level daily and mist the soil as needed. Ensure the soil stays consistently moist but not soggy. Air circulation is vital, especially in a humid environment, so occasionally rotate your trays to promote even growth.

Step 7: Harvesting

Microgreens are generally ready to harvest when they reach about 2-3 inches tall and develop true leaves, typically around 7-21 days post-sowing. Use scissors to cut the stems just above the soil line. You can harvest the greens over several days if they grow at different rates.

Grab a handful of microgreens, rinse them in cold water, and shake off the excess moisture. Store them in a sealed container in the refrigerator for up to a week.

Tips for Success

• Rotate Crops: To ensure continuous harvests, stagger your planting schedules. Start new trays every week or two to have a fresh crop on hand at all times.
• Experiment with Varieties: Try different seed mixes to discover unique flavors and interesting combinations.
• Maintain Cleanliness: Always start with clean containers and tools to prevent mold and pests.

Common Microgreens to Grow

1. Radish: Fast-growing with a peppery taste.
2. Sunflower: Nutty and sweet flavor; requires a bit more space.
3. Pea Shoots: Tender and sweet, they have a unique texture.
4. Basil: Adds a fragrant kick to salads and dishes.
5. Beet Greens: Mildly sweet and vibrant, adding color to your meals.

Troubleshooting Common Issues

• Mold Growth: If you notice mold, ensure proper air circulation and avoid overwatering. A light fan can help with airflow.
• Leggy Growth: If your microgreens are leggy, it typically means they aren’t getting enough light. Move them closer to the light source or increase the light duration.
• Wilting Leaves: This can be a sign of either underwatering or overwatering. Check the soil moisture level and adjust accordingly.
