Microgreens

Amaranth

Amaranthus spp.

Quick step-by-step

  1. Mix the seed with fine sand

    The seeds are tiny: mix them with fine sand to spread them evenly.

  2. Prepare the tray

    Use a 20×40 cm (8×16 in) tray with just 2 cm (0.8 in) of growing medium.

  3. Sow on the surface

    Scatter the mix on the surface without burying it.

  4. Mist very lightly

    Strong watering displaces the tiny seeds: use very light misting only.

  5. Give it intense light

    12 to 14 hours of intense light, which boosts the red-purple color, at 20–28 °C (68–82 °F).

  6. Harvest once the color is even

    Cut once the cotyledons are well colored.

Common mistakes

  • Spreading the seed unevenly

    The tiny seeds are hard to spread by hand; without fine sand, the tray comes out patchy.

  • Burying the seed

    Sow it on the surface, don't bury it.

  • Sowing at a low temperature

    Below 18 °C (64 °F), germination gets irregular.
