Germination
1-2 daysSeeds absorb water and begin sprouting; radicles emerge within 24-48 hours
Keep medium consistently moist; maintain 65-75°F; use a humidity dome or cover tray with damp cloth to retain moisture
Emergence & Cotyledon Development
3-5 daysSeedlings push through soil; first true leaves (cotyledons) unfold, appearing bright green and heart-shaped
Maintain high humidity; provide gentle air circulation; keep soil evenly moist; begin light exposure (reduced intensity initially)
Cotyledon Growth & First Leaves
2-3 daysSeedlings develop true leaf pairs; height reaches 0.5-1 inch; color deepens to dark green
Gradually increase light to 12-16 hours daily; reduce humidity slightly; maintain consistent moisture; ensure good air circulation to prevent mold
Mature Microgreen
2-4 daysSeedlings reach 1-2 inches tall with developed cotyledons and first true leaves visible; texture becomes tender with peppery flavor
Provide full light exposure; maintain optimal moisture without waterlogging; harvest when first true leaves appear or cotyledons are fully developed
Harvest Ready
Peak harvest window: 1-2 daysMicrogreens are 1-2 inches tall, vibrant green, with developed cotyledons and first true leaf set showing characteristic peppery appeal
Harvest with clean scissors just above soil line; use immediately or refrigerate in airtight container for 7-10 days

Harvest Tips
Harvest at 7-14 days when microgreens reach 1-2 inches tall and have developed cotyledons and first true leaves. Cut just above the soil line with clean scissors early in the morning for best flavor and texture. Rinse gently if desired and use immediately or store in an airtight container in the refrigerator for up to 10 days. Rinse just before eating to maintain crispness.
Fun Facts
- 🌱 Arugula microgreens can be regrown once after first harvest by cutting above the soil line and allowing them to regenerate for a second, smaller harvest within 5-7 days.
- 🌱 Arugula microgreens contain up to 50 times more glucosinolates (cancer-fighting compounds) per gram than mature arugula leaves due to their concentrated nutrient profile.
- 🌱 A single 10x20 inch tray of arugula microgreens can yield 1.5-2 pounds of harvest in just 10-14 days with minimal space, making it one of the most efficient crops for indoor urban farming.
