Preparing the Growing Medium

Microgreens can be grown on a variety of growing mediums, such as soil, coconut coir, or grow mats made from natural fibers like hemp or jute. To prepare the growing medium, soak it in water and place it into the 10x10 tray with holes. The growing medium should be moist but not saturated.

Planting the Seeds

After preparing the growing medium, evenly distribute the microgreen seeds across the surface. It's essential not to overcrowd the seeds, as this can lead to issues with mold and uneven growth. Once the seeds are evenly distributed, lightly mist them with water to help with germination.


Germinating the Seeds

Cover the seeded 10x10 tray with another tray without holes or ahumidity dome to create a dark, moist environment for germination. Place the tray in a warm area, ideally between 65°F and 75°F. Check on the seeds daily, and mist with water as needed to keep the growing medium moist. Most microgreen seeds will begin to germinate within 3-5 days.

How Can I Grow Microgreens in the Smallest Space?

Maximizing Space with Vertical Racks

If you have limited space for growing microgreens, consider using vertical racks to stack multiple 10x10 trays. This allows you to grow more microgreens in a smaller area and can help increase air circulation, reducing the risk of mold and other issues.

Utilizing Windowsills and Countertops

Windowsills and countertops can be great places to grow microgreens in small spaces. Place your 10x10 trays near a window that receives plenty of sunlight, or use supplemental lighting if natural light is limited.

Rotating Trays for Continuous Harvest

To ensure a continuous supply of microgreens, consider rotating trays on a regular basis. When one tray is ready to harvest, start a new tray with fresh seeds. This will help you maintain a steady supply of microgreens while maximizing the use of your available space.

Caring for Your Microgreens

Proper Watering Techniques

Watering microgreens correctly is crucial for their growth and health.  Bottom-watering is the recommended method, as it ensures even coverage and reduces the risk of mold and rot. To bottom-water your microgreens, simply pour water into the tray without holes and place the tray with holes and growing medium on top. The growing medium will absorb the water, providing the microgreens with the moisture they need.

Monitoring Light and Temperature

Microgreens require a consistent environment to grow properly. Ensure that your growing area has a consistent temperature between 65°F and 75°F and that your microgreens receive adequate light. If natural light is limited, consider using supplemental lighting, such as LED grow lights.

Harvesting Your Microgreens

Microgreens are typically ready to harvest when they reach 2-3 inches in height, usually within 10-14 days of planting. To harvest, simply use a pair of clean scissors to cut the microgreens just above the growing medium. Rinse the harvested greens and enjoy them in your favorite dishes.

Troubleshooting Common Microgreen Issues

Mold and Fungi

Mold and fungi can be common issues when growing microgreens. To prevent these problems, ensure proper air circulation, avoid overcrowding seeds, and use the bottom-watering method. If mold or fungi do appear, remove the affected microgreens and adjust your growing conditions to prevent future issues. 

Leggy or Weak Microgreens

If your microgreens appear leggy or weak, it may be due to insufficient light or overcrowding. Ensure that your microgreens receive adequate light and that seeds are not planted too densely.
