General

  • Avoid overwatering to control stretch and disease
  • Control growth with DIF, cool temperature, moisture, and fertilizer
  • Keep feed levels up to keep cotyledons from turning yellow
  • Most varieties can be selected for doubles by leaf shape or color, or seedling size
  • Use 7 days of 38-40°F (3-4°C) after Stage 2 to force selection
  • 4-5 weeks total crop time
