Pre-soaking & Germination
1-2 daysSeeds are hulled sunflower seeds (confection or microgreen varieties); soaked 8-12 hours before spreading; fine white radicles emerge within 12-24 hours
Use hulled seeds only; soak to improve germination speed; keep dark and moist during germination; ensure good air circulation to prevent mold
Sprouting & Root Development
3-5 daysWhite root mass develops; seeds begin to push up; tiny shoots emerging; dense green growth begins; seedling looks like small white mound
Keep blackout cover on if using one to encourage upward growth; maintain consistent moisture; ensure air circulation; increase misting frequency
Stem Elongation & Cotyledon Unfurling
3-5 daysSeedlings push through medium; stems lengthen rapidly; cotyledon leaves begin to unfold and separate; yellow color transitions to green; height reaches 1-2 inches
Remove blackout cover to expose to light; begin regular watering schedule; maintain humidity; provide bright indirect light or grow lights
Full Leaf Development & Peak Harvest Readiness
2-4 daysCotyledon leaves fully open and spread; bright green color established; stems sturdy; true leaves may begin to show at base; plants 1.5-2.5 inches tall; packed with flavor and nutrition
Increase light exposure; reduce watering frequency slightly to avoid excessive moisture; avoid overwatering which can cause mold; ensure good air flow
Harvest
1 dayMicrogreens at peak flavor and nutritional density with fully opened cotyledon leaves and established stems; ready to cut and consume
Harvest in the morning; use sharp scissors to cut just above soil line; rinse gently before use; consume fresh or store in refrigerator for 3-5 days
