Day 1-10
The 10 day process step-by-step.
STEP 1: DAY 1 — SOWING & GERMINATION SETUP
Prepare the Growing Trays
● Use two trays per unit:
○ Top tray: with holes (for drainage and airflow)
○ Bottom tray: no holes (to catch water during bottom watering)
Mix and Add Soil
● Mix 1 gallon of organic soil with 40g of Gaia Green fertilizer.
● Add water gradually until the soil is moist but not soggy.
● Fill the top tray with about 1–2 inches of soil, level it evenly.
Weigh and Sow Seeds
● Weigh and sprinkle 10–30g of seeds (varies by type, e.g., broccoli, radish). ● Distribute seeds evenly, avoiding overlaps to prevent mold.
Press and Mist
● Gently press seeds into soil using your hand or another tray.
● Mist the surface with a spray bottle until damp.
Stack and Cover
● Stack trays up to 6 high, placing a flat tray or board and light weight on top.
● This dark, compressed environment encourages root development.
STEP 2: DAYS 2–4 — GERMINATION PERIOD (DARK PHASE)
Daily Routine
● Unstack trays once daily to check moisture.
● Mist gently if soil is dry.
● Re-stack trays with weight after watering.
️
Conditions to Maintain
● Keep trays in a dark, warm room (21–28°C).
● Ensure no light reaches the trays to avoid premature sprouting.
Learning Emphasis
● Encourage participants to observe changes, record daily tasks, and discuss how seeds begin sprouting under pressure.
STEP 3: DAY 5 — TRANSITION TO LIGHT
Unstack Trays and Expose to Light
● When sprouts begin pushing against the weight tray (usually day 4 or 5), unstack and remove cover trays.
● Transfer trays to a rack under LED grow lights, ensuring 12–16 hours of light per day.
Begin Bottom Watering
● Pour 2 cups of water into the bottom tray daily.
● Avoid watering from above to keep leaves dry and prevent mold.
Check Alignment
● Ensure all trays receive even light and rotate trays if needed.
● Encourage learners to identify healthy growth: upright stems, green leaves, no signs of mold.
STEP 4: DAYS 6–8 — GROWTH PHASE
Maintain Light and Water Routine
● Lights: 12–16 hours/day, turned off at night.
● Bottom water as needed—soil should stay moist but not soggy.
️
Ensure Proper Air Circulation
● Use a small fan or open windows to reduce humidity and mold risk.
● Monitor temperature (21–28°C) and humidity (40–60%) daily.
Track Plant Health
● Observe for color, height (ideally 2–3 inches by Day 8), and any irregularities (yellowing, wilting).
Record Keeping
● Track which seed types grow faster or yield more.
● Encourage students to journal the changes, take photos, or graph growth rates.
STEP 5: DAY 9 or 10 — HARVESTING & PACKAGING
Harvesting Microgreens
● Best done in the morning before watering.
● Cut microgreens just above the soil line using clean scissors.
● Avoid pulling or including soil or roots.
Drying and Cleaning
● If needed, gently blot microgreens with paper towels.
● Clean all trays with mild detergent and disinfectant (vinegar or peroxide solution).
Packaging
● Weigh and place greens into clamshells or biodegradable bags. ● Label each container with:
○ Type of microgreen
○ Harvest date
○ Optional: grower name or school program
