Microgreens are young, tender greens that are packed with flavor and nutrients, making them a popular choice for home gardeners. Growing microgreens indoors allows you to enjoy fresh greens year-round, even if you have limited outdoor space. In this article, we will explore the steps and materials needed to successfully grow microgreens inside.

Setting Up a Microgreens Growing Station Indoors

To begin growing microgreens indoors, you will need to set up a dedicated growing station. Here are the steps to follow:

  1. Choose a suitable location: Select a well-lit area in your home that receives at least 4-6 hours of sunlight per day. Alternatively, you can use artificial grow lights to provide the necessary light.
  2. Assemble the necessary materials and equipment: You will need the following items:
  • Containers: Use 3-inch peat pots or other suitable containers with drainage holes to grow your microgreens.
  • Soilless seed-starting mix: This provides a lightweight and sterile medium for your microgreens to grow in.
  • Vermiculite: Use vermiculite to cover the seeds and promote germination.
  • Seeds of your choice: Select microgreen seeds based on your preferences and desired flavors.
  • Plant labels: Use plant labels to keep track of different varieties of microgreens.
  • Plastic wrap: Covering the containers with plastic wrap helps maintain humidity during germination.
  • Garden trowel: Use a garden trowel to fill the containers with the seed-starting mix.
  • Watering can: Use a watering can to gently water the microgreens.

Step-by-Step Guide to Growing Microgreens Indoors

Now that you have gathered the necessary materials, follow these steps to grow microgreens indoors:

  1. Dampen the soilless seed-starting mix: Sprinkle warm water onto the mix and blend until thoroughly damp.
  2. Fill each container: Fill each container with the premoistened seed-starting mix, leaving some space for the seeds.
  3. Sprinkle the seeds: Sprinkle the microgreen seeds evenly over the surface of the mix, sowing them more thickly than usual.
  4. Cover the seeds: Follow the planting depth instructions provided on the seed packet and cover the seeds with vermiculite.
  5. Label the plantings: Use plant labels to identify the different varieties of microgreens.
  6. Water the seeds: Gently water the seeds, making sure not to wash them away.
  7. Cover the containers: Cover the containers with plastic wrap or a dome lid to maintain humidity and promote germination.
  8. Place the containers in a sunny spot: Position the containers on a sunny windowsill or under artificial grow lights.
  9. Water from the bottom: Water the microgreens by pouring water into the drip tray and allowing it to be absorbed into the soilless mix.
  10. Monitor and care for the microgreens: Keep an eye on the moisture levels and adjust watering as needed. Remove the cover and heat source once the seeds germinate, and continue to care for the plants by watering as needed.
  11. Harvest the microgreens: When the microgreens reach the desired size, harvest them by holding a section with one hand and snipping with scissors. Store them in an airtight container in the refrigerator until ready to use.
