How to Grow Kohlrabi Microgreens at Home

1. Prepare Your Tray:
   Fill a 10×20-inch tray with sterile soilless media like coconut coir, fine vermiculite, or hemp mats.
2. Sow Seeds:
   Scatter organic, pathogen-free kohlrabi seeds evenly and densely.
3. Germinate:
   Cover with a blackout lid for 3–4 days at 65–75°F, keeping moisture steady through bottom watering or misting.

   After sprouting, place under LED grow lights (14–24 hours daily) or indirect sunlight, 8–12 inches above the tray. Use fans to reduce mold risk.
5. Harvest:
   Cut microgreens at 1–3 inches tall (7–14 days), just above the growing medium.
6. Store:
   Keep unwashed in ventilated or airtight containers at 32–39°F for 7–10 days.
