Microgreens Grow Guide
Prepare & Plant
- Measure 1–2 teaspoons of seeds per 5x5-inch tray (use 1.5–2 teaspoons for larger seeds like sunflower).
- Spread seeds evenly on a thoroughly moistened growing medium (such as coconut coir or soil).
- Optional: Soak seeds for 4–12 hours before planting to jump-start germination, especially beneficial for larger seeds.
Cover & Germinate
- Cover the tray with another tray or a plate to keep out light and retain moisture.
- Place the tray in a dark, warm area for 2–4 days until you see the seeds beginning to sprout.
Watering
- Lightly mist the growing medium as needed to keep it moist, but avoid overwatering. Coconut coir often requires less frequent watering due to its moisture-retaining properties.
- For seeds like wheatgrass, you may want to mist more regularly, as they tend to absorb more water.
- When sprouts start to show leaves (around days 2–4), remove the cover and move the tray to a well-lit location with indirect sunlight or place it under a grow light.
- Continue misting lightly 1–2 times daily to keep the soil evenly moist.
Harvest
- Microgreens are ready when they reach 1–3 inches in height and their leaves are open (typically day 5–14).
- Wheatgrass should be harvested at 4–5 inches for juicing.
- Use scissors to cut just above the soil.
- For optimal freshness, store harvested microgreens in a sealed container in the refrigerator and use within 1–3 days.
Additional Tips
- For Larger Seeds: Sunflower and wheatgrass may require slightly more seeding (1.5–2 teaspoons) and a longer harvest period (days 8–14).
- Growing Medium: Coconut coir is a great option for all seed types and may reduce the need for watering after planting.
- Harvest Timing: Keep an eye on growth. Smaller varieties like radish and clover may be ready sooner, while sunflower and wheatgrass generally need a few extra days.
