Growth Stages

1

Soaking

4-8 hours

Seeds are soaked in water for 4-8 hours to initiate germination

Use room-temperature water; drain well before spreading on soil

2

Germination

2-3 days

Seeds develop root growth and initial shoot emergence; white radical appears beneath soil surface

Keep soil moist, maintain darkness or low light, ensure good air circulation to prevent fungal issues

3

Sprouting/Seedling

3-5 days

Cotyledons (seed leaves) emerge and begin photosynthesis; tiny first true leaves visible

Introduce bright indirect light gradually, maintain consistent moisture, ensure adequate ventilation

4

Leaf Development

3-7 days

True leaves develop, plant grows upright with characteristic frilly foliage; color deepens to green

Maintain 12-16 hours of light daily, water from below, monitor for mold or pest issues

5

Harvest Ready

At peak (day 7-14)

Plants reach 1-2 inches tall with fully developed cotyledons and emerging true leaves; optimal flavor and texture achieved

Harvest when first true leaves are visible but before they fully expand for best tenderness

Harvest Tips

Harvest when microgreens are 1-2 inches tall (typically day 7-14), just as the first true leaves begin to emerge. Cut at soil level using clean scissors or a sharp knife. Harvest in the morning after leaves have dried from misting. Use immediately or store in a refrigerator in an airtight container for up to 5-7 days. For best flavor, harvest before fully expanded true leaves develop.
