Microgreens Production Guide

Workflow

1. 1

   Calculate Seed Density and Tray Count

   1 hour

   Select grams per tray for variety, calculate trays needed for weekly sales target, and plan soak time for mucilaginous seeds.

2. 2

   Set Light Height and Photoperiod

   30 minutes

   Hang lights at PPFD for microgreen stage, run 16–18 hour photoperiod, convert to DLI to compare varieties.

3. 3

   Grow, Monitor, and Harvest at Cotyledon Peak

   7–14 days per tray

   Bottom-water to keep leaves dry, harvest at first true leaf for most varieties, weigh yield per tray for density refinement.

   Scale Tray Count to Sales and Delivery

   Ongoing

   Use yield estimator to scale tray count, schedule seeding dates backward from delivery day, track power cost per tray.

Tools Used

• Microgreen Tray Density
  Primary

  Calculates seed weight per 1020 tray for variety-specific optimal density.

• Grow Light PAR Calculator
  Primary

  Sets LED height for 150–300 PPFD typical microgreen range.

• PPFD to DLI Converter
  Supporting

  Verifies daily light integral across photoperiod for consistent quality.

• Seed-to-Harvest Timer
  Reference

  Schedules seeding date backward from delivery for peak freshness.

Reference Materials

• Stabilize pH First

  Adjust pH before adding nutrients — pH drift after mixing wastes expensive inputs.

• Root Zone Temp

  Keep reservoir 65–70°F — warmer water holds less oxygen and invites root rot.

• Electrical Safety

  Drip loops on all cords entering reservoirs and GFCI on every outlet.
