Germination
1-3 daysSeeds absorb moisture and split, showing white radicles emerging from seed coat
Keep substrate moist and maintain darkness or low light for 2-3 days to encourage germination; maintain temperature around 65-75°F
Emergence
2-3 daysSeedlings push through soil, developing hypocotyl (seed stem) and beginning to establish root system
Maintain moisture; begin introducing light gradually; ensure good air circulation to prevent mold; avoid direct strong light
Cotyledon/True Leaf Development
3-8 daysFirst true leaves emerge above cotyledons; microgreens develop characteristic color and texture; peppery aroma becomes noticeable
Provide 12-16 hours of bright light daily; maintain consistent moisture; ensure air circulation with small fan; temperature 65-75°F optimal
Harvest-Ready
Ready for harvestMicrogreens reach 1.5-2 inches tall with expanded cotyledons and visible true leaves; vibrant green color and full spicy flavor developed
Reduce watering slightly 24 hours before harvest to improve shelf life; prepare clean scissors or knife for harvesting; harvest in morning when moisture is high
