  • Radish microgreens will be ready to harvest 8 days after planting
  • Humidity dome needs to be removed 50 hours after planting
  • No additional watering should be needed (this needs to be tested in the unit)
  • Water stayed visibly in the flood tray until 4 or 5 days after initial planting
  • Soil will shrink down from the indicator line and might make harvesting more challenging (this will need further testing, we may want to raise the indicator line or shorten the tray, we could also do two separate trays further down the road – one optimized for microgreens)
  • These microgreens were grown in an open air shelf with temperature around 23 degrees and 49.5 relative humidity
  • One tray will yield approximately 150g of radish microgreens
  • Serving size for radish microgreens is approximately 10g
