  • Soil Temperature: Keeping your soil at an optimal temperature will help encourage healthy growth for your microgreens. A good range to aim for is between 55°F – 70°F (12°C – 21°C).
  • Nutrient Deficiencies: If you notice any yellowing or stunted growth, there could be nutrient deficiencies present in the soil. To fix this, add fertilizer or compost as needed.
  • Light Requirements: Microgreens need plenty of light for photosynthesis. Make sure they are getting 6-8 hours of direct sunlight per day or use artificial lights if necessary.
