Getting Started

Mass Seedling Guide

Build a repeatable seedling workflow that produces dozens of healthy starts at once without losing track of watering, spacing, or light levels.

⏱️ Time required: 1–2 hours to set up, then daily checks through the germination and early seedling stage.

Why Scale Seedlings

Scaling is mostly about consistency: the same tray format, the same growing mix, the same watering approach, and the same light height for every batch.

What You Need

Batch Workflow

1. Organize before you plant

  1. Label every tray with crop name, batch date, and any treatment notes.
  2. Pre-fill cells evenly so the media depth is consistent across the tray.
  3. Group seeds by crop or variety when germination timing differs meaningfully.
  4. Set timers for heat and lights before any seed goes in the tray.

2. Seed placement at scale

  1. Use tweezers, a seed board, or a vacuum seeder to place seeds consistently.
  2. Keep spacing uniform so each plant has similar access to water and light.
  3. Cover lightly and mist instead of pouring water directly on the tray.
  4. Record the batch size so you can track germination percentage later.

3. Light and moisture control

  1. Keep the tray evenly moist, not saturated.
  2. Start lights at a safe distance, then adjust once seedlings are established.
  3. Open domes daily to exchange air and reduce mold pressure.
  4. Use a fan on low to strengthen stems without drying the tray.

4. Cull and transplant

  1. Remove weak or stalled seedlings early.
  2. Transplant once roots fill the cell but before the tray becomes root-bound.
  3. Move strong plants into larger containers or final beds in a single batch.
  4. Keep one log per batch so future runs are easier to compare.
