Equipment

  • Heat mat (optional)

Materials

  • Tomato seeds
  • Seed starting mix
  • Seed starting trays or pots
  • Water

Instructions

  • Mix the seed starting mix with warm water until it’s well moist but not soggy. It should just hold together when you squeeze it into a ball.
  • Fill your planting containers, and press the soil down firmly to remove any large air-spaced but don’t compact it.
  • Place 2 seeds into each cell and cover with about 1/4 inch of soil. Gently press the soil down so that it has good contact with the seeds.
  • Water or mist from the top to moisten the new top layer of seed starter that you covered the seeds with.
  • Cover with a plastic dome over your seed starting trays to help hold in the moisture. Alternatively, you can use plastic wrap from your kitchen to lay over top.
  • Place the seed trays in a warm place, on a heat mat, on top of the fridge or a sunny window. At this stage, they don’t need light, but they do need warmth to germinate.
  • Water as needed to make sure the soil is moist but not soggy.
  • Check the plant trays daily and when the seeds start to germinate remove the plastic dome and place them under your grow lights or in a sunny window.
