  • What You'll Need

    Soil and Tray Method

    Seed Starting Supplies 
  • Plant your Seeds

    1. Pre-saturate your seed starting soil mix. Ensure the seed starting mix is fully saturated prior to planting your seed.
    2. Make a ¼-inch hole in the center of each seed starting cell. A #2 pencil eraser is a great tool for making these holes.
    3. Place your seed and cover gently with soil.
      You can plant up to 4 seeds per cell to help ensure successful germination.
  • 4. Place your heat mat under  your base tray and your humidity dome on top. For best results, set your temperature controller between 75 - 80 degrees.

    5. Place your plant light above the seed starting tray and turn on. Refer to the plant light manufacturers instructions for the optimal distance. Plant light should remain on for 14 to 16 hours per day.
