Planting Instructions for Wheatgrass – Hydroponic (Soilless) Method


🌾 Supplies Needed

  • Hard red winter wheat or wheatgrass seeds
  • Shallow tray with drainage (or sprouting tray with mesh)
  • Growing mat (hemp, coconut coir, or paper towel)
  • Spray bottle
  • Clean water
  • Optional: blackout dome or second tray to cover

🪴 Step-by-Step Instructions

1. Soak the Todd’s Seeds Wheatgrass Seeds

  • Rinse and soak seeds in cool water for 8–12 hours (overnight).
  • Drain, rinse again, and let rest for another 8–12 hours until just sprouting.

2. Prepare the Tray

  • Lay your growing mat or 2–3 layers of paper towels on the bottom of the tray.
  • Moisten thoroughly so the surface is damp but not soaking.

3. Sow the Seeds

  • Spread the pre-sprouted seeds evenly across the surface.
  • Gently press them down for good contact with the mat, but do not cover with more material.

4. Cover & Germinate

  • Cover the tray with another tray or dome to block light and hold in moisture.
  • Place in a dark, warm area (65–75°F) for 2–3 days.
  • Mist seeds 1–2 times daily to keep evenly moist.

5. Uncover & Grow

  • When shoots are 1–2 inches tall, remove the cover and move to bright, indirect sunlight or a grow light.
  • Continue misting or bottom watering once or twice daily to keep the mat moist (not soggy).

6. Harvest

  • Harvest when blades are 6–8 inches tall—usually 7–10 days after sowing.
  • Cut just above the mat with clean scissors.

7. Second Cut (Optional)

  • You may get a smaller second harvest within a few days. After that, compost the mat and roots.

🧊 Storage

  • Store cut wheatgrass in a sealed container in the refrigerator for up to 3 days.
  • Rinse before juicing or blending.

Tips:

  • Use filtered water for best results.
  • Clean trays thoroughly between uses to prevent mold.
