Grow Microgreens: How to Grow Microgreens Indoors — Microgreens are tiny plants packed with flavor and nutrients. Growing them indoors is a simple way to enjoy fresh, healthy greens all year long without needing a garden or fancy tools.
Why Growing Microgreens Indoors Is a Game Changer
Microgreens grow fast, need little space, and deliver high nutrition in every bite. They are ideal for apartments or homes with limited sunlight because they thrive under basic indoor light. These young seedlings contain up to 40 times more vitamins and minerals than mature greens. Whether it’s winter or summer, you can grow and harvest them weekly for salads, sandwiches, or smoothies.

Not all greens grow the same indoors, but some perform exceptionally well. Choose varieties that sprout quickly and taste great:

Step-by-Step Guide to Grow Microgreens Indoors
- Step 1: Choose Your Seeds and Tray
Start with organic, untreated microgreen seeds. Use a shallow tray with drainage holes, around 1–2 inches deep. You can even reuse old food containers after poking small holes at the bottom. Clean the tray thoroughly before planting to avoid mold growth.
- Step 2: Prepare the Soil or Growing Medium
Fill the tray with a fine potting mix or coco peat about an inch deep. Moisten the surface using a spray bottle until it’s damp but not soggy. A light, fluffy texture allows roots to spread easily and absorb nutrients effectively.
- Step 3: Sow Seeds Evenly
Sprinkle seeds evenly across the soil surface—don’t overcrowd. Lightly press them into the soil using your palm. Avoid covering them too deeply; a thin layer of soil or a gentle mist of water is enough to encourage germination within 2–3 days.
- Step 4: Create Ideal Growing Conditions
Place the tray in a warm spot with indirect sunlight or under LED grow lights. Cover the tray with a lid or another tray for the first two days to maintain humidity. Once seeds sprout, uncover and keep them under light for at least 10–12 hours daily.
- Step 5: Water and Care Daily
Mist the microgreens gently every morning to keep the soil moist but not waterlogged. Avoid overwatering as it may cause fungus. Ensure good air circulation around the tray to keep the greens fresh and prevent mold.

Your microgreens will be ready in 7–14 days, depending on the type. Use scissors to snip just above the soil line. Rinse gently under cool water and pat dry. Enjoy them immediately for maximum freshness and flavor.
Extra Tips for Successful Indoor Microgreen Gardening
- Use filtered water for misting to prevent mineral buildup.
- Rotate trays daily to ensure even light exposure.
- Keep lights 6–8 inches above the plants for balanced growth.
- Harvest just before watering to keep greens crisp.
- Replant fresh seeds every week for a continuous supply.
