Black Mustard Microgreen Seeds - 10 Gram

Black Mustard Microgreens are fast-growing, spicy, and flavour-packed shoots with deep green leaves and purplish stems. They have a bold, peppery flavour similar to horseradish or strong rocket, making them excellent for adding heat and complexity to dishes. Rich in vitamins A, C, K, antioxidants, and anti-inflammatory compounds, these microgreens are as nutritious as they are vibrant.

How to Grow Black Mustard Microgreens

What You’ll Need

Shallow tray (3–5 cm deep) with good drainage

Fine seedling mix, coco coir, or sterile potting soil

Spray bottle or bottom-watering tray

Black mustard seeds (no soaking needed)

Sowing Instructions

Fill the tray with moist growing medium to 3–4 cm deep.

Sprinkle seeds evenly and densely across the surface.

Press seeds gently into the surface for good contact, but do not cover with soil — mustard seeds need light to germinate.

Mist thoroughly with a spray bottle.

Cover the tray with a lid or second tray for a blackout period of 2–3 days.

After Germination

After 2–3 days, when seeds have sprouted, remove the cover.

Place the tray in bright indirect sunlight or under grow lights.

Provide 12–16 hours of light daily to promote strong, upright growth.

Watering

Mist daily, or better, bottom-water by placing your tray in a shallow tray of water for a few minutes.

Keep the soil consistently moist, but never soggy.

Harvesting

Harvest in 7–10 days, when microgreens are 5–8 cm tall and have developed their first true leaves.

Cut with clean scissors just above the soil surface.

Best harvested in the cool of the morning for maximum crispness and shelf life.
