Step 1: Gather Your Supplies
- Mustard microgreen seeds: Choose your preferred variety.
- Growing tray: A shallow, leak-proof tray; drainage not required.
- Growing medium: Soilless mixes (coconut coir, peat) or hydroponic mats.
- Mister or spray bottle: For gentle watering.
- Light source: Natural sunlight, LED grow lights, or a bright windowsill.
- Optional: A humidity dome or cover.
Step 2: Prepare the Growing Tray
- Fill the tray with about 1â2 inches of growing medium, leveling the surface but not compressing it.
- Moisten the medium thoroughly, ensuring it is damp but not soggy.
Step 3: Sow the Seeds Evenly
- Scatter mustard seeds evenly across the surface; do not bury them.
- For uniform density and growth, avoid clumpingâoverlap is fine as microgreens thrive densely.
- Mist lightly to settle seeds onto the medium.
Step 4: Germinate in Darkness
- Cover the tray with a lid, another tray, or a humidity dome to block light and retain moisture.
- Keep the tray at room temperature (65â75°F / 18â24°C).
- Check daily for moisture; mist if the surface dries out.
- Seeds typically sprout in 1â2 days.
Step 5: Grow and Harvest
- Once most seeds have germinated, remove the cover and expose the tray to strong light.
- Microgreens will green up and elongate toward the light.
- Water regularly (prefer bottom watering or gentle misting to prevent mold).
- Harvest when the first set of true leaves appear, usually in 6â7 days.
To harvest, snip the greens just above the root line using sanitized scissors. Rinse and use immediately, or pat dry and store in a sealed container in the fridge for up to a week.
Tips for Growing Success
- Dense seeding: Mustard microgreens thrive packed together, but ensure good airflow to prevent disease.
- Light importance: Microgreens grown in low light will be pale and leggy. Use a bright window or LED grow lights for best results.
- Watering: Keep the growing medium moist, but not waterlogged. Water from the bottom to minimize mold.
- Avoid soil compaction: Lightly spread the growing medium; do not press it down, as roots need air.
- Harvest timing: Microgreens taste best before the true leaves fully develop and grow tougher.
Common Problems and Solutions
| Issue | Cause | Solution |
|---|---|---|
| Mold or Fungus | Overwatering, poor airflow | Reduce watering, introduce gentle airflow, avoid crowding |
| Pale, Leggy Growth | Insufficient light | Provide stronger light source or move tray to brighter spot |
| Poor Germination | Dry medium, old seeds | Ensure thorough pre-watering, use fresh seeds |
| Wilted Microgreens | Dried out medium | Mist or water consistently, avoid letting medium dry |
