What Are Microgreens?
Microgreens are young vegetable and herb plants harvested shortly after germination, usually when they develop their first true leaves.
They grow after sprouts but before baby greens, making them the perfect balance between nutrition, flavor, and convenience.
Unlike sprouts:
- Sprouts grow only in water.
- Microgreens grow in soil or another growing medium.
- Only the stem and leaves are eaten.
- They have stronger flavors and higher nutrient density.
Popular varieties include:
- Broccoli
- Radish
- Sunflower
- Pea Shoots
- Kale
- Arugula
- Cilantro
- Basil
- Mustard
- Amaranth
Why Should You Grow Microgreens?
Research has shown that many microgreens contain significantly higher concentrations of vitamins and antioxidants than their mature counterparts.
Benefits include:
- Rich in Vitamin C
- High in Vitamin K
- Excellent source of antioxidants
- Supports immune health
- May reduce inflammation
- Easy to digest
- Ready in under two weeks
- Requires very little growing space

5. LED Grow Lights
Microgreens require around:
- 12–18 hours of light daily
LED shop lights are inexpensive and produce compact, healthy plants.
Step 1: Prepare Your Growing Tray
Fill your tray with moist soil.
Leave approximately ½ to 1 inch below the rim.
This makes harvesting much easier.
Level the surface without compacting the soil too much.
Step 2: Sow the Seeds
Spread seeds evenly.
Avoid overcrowding.
Seed Soaking Guide
| Seed | Soak Time |
|---|---|
| Peas | 6–12 hours |
| Sunflower | 4 hours |
| Radish | No soaking |
| Broccoli | No soaking |
| Kale | No soaking |
Mist lightly with water.
Step 3: The Blackout Phase
Cover the tray using:
- Another tray
- Humidity dome
- Blackout cover
Add a light weight such as:
- Brick
- Stone
- Book
Leave covered for:
3–4 days
This encourages:
- Strong roots
- Even germination
- Thick stems
Don’t worry if seedlings appear yellow.
Once exposed to light, chlorophyll develops quickly.
Step 4: Provide Proper Lighting
Move trays beneath LED lights.
Keep lights:
- 2–4 inches above plants
Lighting schedule:
12–18 hours daily
Without enough light, microgreens become:
- Tall
- Weak
- Leggy
Step 5: Bottom Water Correctly
Bottom watering is the secret to healthy microgreens.
Instead of watering from above:
- Pour water into the bottom tray.
- Let soil absorb moisture naturally.
- Remove excess water after 15–20 minutes.
Benefits include:
- Prevents mold
- Reduces fungus
- Stronger roots
- Cleaner leaves

When to Harvest Microgreens
