Germination
2-3 daysSeeds absorb moisture and begin sprouting; white radicles appear
Keep soil moist and cover tray with humidity dome or damp cloth; maintain 65-75°F; check daily for germination
Cotyledon Development
3-5 daysFirst leaves (cotyledons) emerge and unfold; seedlings appear as tiny green sprouts
Maintain moisture, increase air circulation, remove cover if condensation builds; begin light exposure
Cotyledon Expansion
3-5 daysCotyledons fully expand and darken green; seedlings develop characteristic radish color and texture
Provide full light (12-16 hours daily); maintain 60-70% soil moisture; ensure good air flow to prevent damping off
True Leaf Emergence
2-3 daysFirst true leaves (more serrated and smaller than cotyledons) begin to show between the cotyledons
Increase light intensity; maintain consistent moisture; harvest can begin at this stage or wait for fuller growth
Harvest Ready
Ready after day 7-14Microgreens reach 1-2 inches tall with developed cotyledons and possibly first true leaves; full peppery flavor developed
Harvest when color is vibrant and stems are sturdy; use sharp scissors to cut at soil level

Harvest Tips
Radish microgreens are ready to harvest 7-14 days after sowing when cotyledons are fully developed and 1-2 inches tall. Cut at soil level using clean, sharp scissors. Harvest in the morning after any excess moisture has dried for best quality. They can be harvested at the cotyledon stage for milder flavor or allowed to develop first true leaves for more peppery intensity. Store harvested microgreens in airtight containers in the refrigerator for 5-10 days.
