Description: Organic seeds for growing baby greens indoors through winter. Black Seeded Simpson is a popular green loose-leaf lettuce that is adaptable to many growing situations including indoor baby greens. The leaves are tender and tasty!

Easy steps for growing Black Seeded Simpson Lettuce greens indoors through winter:

  • Lettuce grows most productively under full spectrum (6400K) grow lights. We recommend Sunblaster T5 lighting. Grow lights should be maintained 6 - 12” above plant tops and should be on 16 - 18 hours per day.
  • During the months where daylight-hours are low lettuce can be grown in a very sunny window - but productivity goes way up under full-spectrum lights.
  • Baby lettuce grows very well in shallow containers with drainage. We often use 11 x 11” or 10 x 20” trays. Other ideas include recycled clam shells from store-bought greens or recycled flower pots.
  • For completely easy baby greens use a composty soil. We use an organic potting mix blended with Sea Soil compost at a 60 / 40 ratio. By building in high-quality compost you can avoid any need for additional fertilizing.
  • Black Seed Simpson Lettuce takes 3 - 5 days to germinate. The ideal temperature for germination is 12 - 18º C; bottom heat will speed up germination and encourage faster seedling development but excessively warm soil temperatures inhibit germination of lettuces.
  • Wet your soil medium before sowing then sprinkle seeds onto soil surface at approximately 350 seeds per 11 x 11” tray. Press seeds gently into soil surface and spritz (or carefully water) to fully moisten.
  • Check on seeds every few days to notice when they are starting to germinate. Maintain soil moisture without allowing the mix to be soggy.
  • Baby lettuce will grow as a baby green for approximately eight to ten weeks before a new crop needs to take over. Sow new trays every 2 - 4 weeks to keep a constant supply.

    Additional Tips:

    • Great air circulation around your indoor garden makes everything better! If you are growing lots of plants indoors consider adding a small fan to your set-up.
    • If using humidity domes over your trays: be sure to leave these off for at least one hour per day to allow for air circulation.
    • Pests rarely occur on baby greens but it is a good idea to clean pots/trays with warm soapy water (or 10% bleach solution) between crops and generally keep your growing area tidy.
    • Crops that are grown to larger than baby green size will likely require fertilizing for best productivity; we recommend Evolve Organic All-Purpose Fertilizer for our indoor gardens.

    Harvesting Tips:

    • Harvest leafy greens by up to 50% with each cut.
    • Use sharp scissors to cut your greens - this helps plants regrow more quickly after harvest.
    • The beauty of growing your own baby greens is that you can harvest just what you need when you need it!
