Popular varieties include radish, kale, broccoli, sunflower, and pea shoots.

Step-by-Step Guide to Growing Microgreens Indoors
Step 1: Select and Prepare Seeds
Opt for easy-to-grow varieties such as radish, sunflower, or broccoli.
Soak larger seeds like peas and sunflowers for 6–12 hours to improve germination.
Step 2: Prepare the Growing Tray
Fill your tray with about 1–2 inches of your chosen growing medium.
Level the surface to ensure even seed distribution.
Step 3: Sow the Seeds
Sprinkle seeds evenly across the surface without overcrowding.
Gently press the seeds into the medium, ensuring good seed-to-soil contact.
Step 4: Water Gently
Mist the seeds lightly with a spray bottle until the growing medium is evenly moist.
Step 5: Cover the Tray
Use a plastic dome or another tray to cover the seeds, creating a humid environment for germination.
Step 6: Monitor and Water
Check daily for signs of germination and ensure the soil remains moist (not waterlogged).
Remove the cover once the seeds sprout, usually within 2–5 days.
Step 7: Provide Adequate Light
Place the tray in a sunny window or under grow lights for 12–16 hours daily.
Rotate the tray occasionally to encourage even growth.
Step 8: Harvest Your Microgreens
Most varieties are ready to harvest 7–14 days after planting, once they have developed their first true leaves.
Use sharp scissors to cut the greens just above the soil line.
