Quick answer: To grow microgreens at home, spread seeds densely over a tray of moist potting mix, keep them dark for 2–3 days, then move them into bright light. Fast varieties like radish and mustard are ready to harvest at the first-leaf stage in about 7–10 days.

What Are Microgreens?

Microgreens are young vegetable and herb seedlings harvested just after their first leaves appear, usually 7–14 days after sowing. They are packed with flavour and nutrients and are one of the quickest, most rewarding crops to grow indoors, even without a garden.

What You Need

You need a shallow tray, a thin layer of potting mix or coco peat, and seeds. Seedling trays such as protrays work well, and a mix enriched with a little compost gives sturdy growth. A spray bottle for gentle watering completes the kit.

Best Fast Microgreens for 7 Days

For the quickest harvest, choose fast germinators. radish seeds and mustard seeds sprout and grow rapidly, often ready in about a week. fenugreek (methi) is another speedy, popular choice, while sunflower and basil seeds give satisfying, flavourful greens in a little more time.

Step-by-Step Method

Spread the seeds densely and evenly across the moist surface, but not piled on top of each other. Press them down lightly and mist well. Cover the tray or keep it in the dark for two to three days so the seeds germinate, then move it into bright, indirect light to green up.

Watering and Avoiding Mould

Mist once or twice a day to keep the surface moist but never waterlogged, and ensure good airflow. Overwatering and stagnant air cause mould and damping-off. Note that fine white root hairs are normal and are often mistaken for mould; true mould looks fuzzy and web-like.

Harvesting Your Microgreens

Harvest when the first true leaves appear, usually 7–10 days for fast varieties. Snip the stems just above the soil with clean scissors, rinse, and eat fresh. Microgreens don't regrow after cutting, so sow a new tray every few days for a steady supply.

Microgreens vs Sprouts

People often confuse microgreens with sprouts, but they are different. Sprouts are germinated seeds eaten whole, including the root, and are grown in water without soil or much light. Microgreens are grown in a thin layer of soil or medium, given light to develop leaves, and harvested by snipping the stems above the soil. Microgreens generally carry a lower food-safety risk than sprouts because they are cut above the growing medium.

Keep It Clean and Fresh

Cleanliness keeps your microgreens healthy and safe to eat. Use clean trays and fresh growing medium, water with clean water, and ensure good airflow to prevent mould. Harvest with clean scissors, rinse the greens, and eat them soon after cutting for the best flavour and texture. Store any extra in the fridge and use within a few days.

Frequently Asked Questions

Which microgreens grow fastest?

Radish, mustard, and cress are among the fastest, often ready in about 7–10 days.

Do microgreens need sunlight?

After germinating in the dark, they need bright light, indirect sun or a grow light, to green up.

Is the white fuzz on my microgreens mould?

Often it is harmless root hairs near the stem base. True mould is fuzzy, spreads, and smells musty.

Can I regrow microgreens after cutting?

Most do not regrow. Sow fresh trays regularly for a continuous harvest.

Do I need special seeds for microgreens?

You can use ordinary vegetable and herb seeds. Just sow them densely, as you harvest at the seedling stage.

How do I store harvested microgreens?

Rinse, pat dry, and keep them in the fridge in a container; use within a few days for the best freshness.
