Microgreens are young vegetable greens that are harvested just after the first true leaves have developed. They are packed with nutrients and add vibrant flavors and textures to a variety of dishes. Growing microgreens can be a rewarding activity, especially during the winter months when outdoor gardening options are limited.
What Are Microgreens?
Microgreens are harvested typically within 7 to 21 days after germination. They include a diverse range of plants such as basil, radish, sunflower, and beet greens. Due to their small size and intense flavor, microgreens are popular among chefs and home gardeners alike.
Challenges of Growing in Zone 1 During Winter
Zone 1, characterized by very cold winters, presents unique challenges for microgreen cultivation. Temperatures often drop below freezing, making outdoor growing impractical. Additionally, limited daylight hours can hinder plant growth. However, with proper indoor techniques, microgreens can thrive even in these conditions.
Indoor Growing Techniques
Using Grow Lights
To compensate for shorter daylight hours, use grow lights to provide the necessary 12-16 hours of light daily. LED grow lights are energy-efficient and effective for microgreen growth.
Optimal Temperature and Humidity
Maintain indoor temperatures between 18°C and 24°C (65°F to 75°F). Keep humidity levels moderate to prevent mold and ensure healthy germination.
Step-by-Step Growing Guide
- Choose a shallow container with drainage holes.
- Fill the container with a quality potting mix or seed-starting medium.
- Sow the microgreen seeds evenly across the surface.
- Lightly cover the seeds with a thin layer of soil or press them gently into the surface.
- Water gently to keep the soil moist but not waterlogged.
- Place under grow lights or near a sunny window.
- Maintain consistent moisture and monitor growth daily.
- Harvest when the microgreens are 1-3 inches tall, usually within 7-14 days.
