Herb Microgreens
Various species (mixed herb microgreens)
herbMicrogreens are young herb seedlings harvested at the cotyledon or early true-leaf stage, typically 7-14 days after germination. They are nutrient-dense, flavorful additions to culinary dishes grown in compact indoor spaces with minimal water and light. Common varieties include basil, cilantro, parsley, dill, and chives microgreens.

Germination
2-4 daysSeeds absorb water and begin sprouting; radicle emerges and roots develop into the growing medium
Keep medium moist and maintain 65-75°F temperature; cover with a humidity dome or cloth to retain moisture for 2-4 days
Emergence
2-3 daysCotyledons (seed leaves) break through the surface; seedlings appear as tiny pale shoots with unfurled first leaves
Remove humidity cover once majority have emerged; provide gentle misting; begin introducing light if using grow lights at lower intensity
Cotyledon Development
3-5 daysTrue cotyledons fully expand and strengthen; seedlings develop green coloration from chlorophyll and begin forming first true leaves
Increase light exposure to full 12-16 hour photoperiod; maintain consistent moisture; ensure adequate air circulation with a small fan to prevent damping-off
True Leaf Formation
2-4 daysFirst set of true leaves (characteristic herb leaves) begin to emerge above cotyledons; flavor and nutrient density peak; microgreens reach harvestable size
Continue full light and ventilation; reduce watering frequency slightly as leaves increase transpiration; harvest when true leaves are 1-2 inches tall for peak nutrition and flavor
Harvest Ready
1 day (optimal harvest window)Microgreens display full cotyledons with emerging true leaves; plants are 1-2 inches tall with vibrant green color and developed herb aroma
Harvest in the morning when plants are fully hydrated; use clean scissors to cut just above soil line; rinse gently and use immediately for best flavor

Common Pests
-
Ensure excellent air circulation with fan; avoid overwatering; use sterile growing medium; maintain 50-70% humidity (not higher); discard affected trays immediately
-
and
Increase air circulation; reduce humidity if above 70%; ensure light reaches all areas of tray; remove visible mold with sterile tools
-
Allow soil surface to dry slightly between waterings; use yellow sticky traps; avoid decomposing organic matter in medium; maintain clean growing environment
Uses
Salads, Garnishes & Plating
CulinaryHerb microgreens add vibrant color, concentrated flavor, and visual appeal to salads, soups, sandwiches, and plated dishes. Their delicate leaves provide a fresh, intensified taste of their mature herb counterparts in a tender, edible package. [source]
Smoothies & Beverages
CulinaryBlend basil, cilantro, or parsley microgreens into smoothies, juices, and detox drinks for a nutrient boost without the bitterness of mature herbs. The tender leaves blend smoothly and impart fresh herbal notes. [source]
Concentrated Nutrients & Antioxidants
MedicinalMicrogreens contain 4-40 times higher concentrations of vitamins, minerals, and antioxidants than their mature plant counterparts. They provide bioavailable phytonutrients, chlorophyll, and polyphenols for immune support and anti-inflammatory benefits. [source]
Year-Round Indoor Growing
HouseholdMicrogreens can be grown indoors year-round without outdoor space, soil, or pesticides, making them ideal for apartments, offices, and urban environments. Successive planting every 1-2 weeks provides continuous fresh harvests. [source]
Educational & Hobby Growing Project
CraftGrowing microgreens is a fast, rewarding project for children and beginners to learn plant biology, seed germination, and food production with visible results in less than two weeks. [source]

Harvest Tips
Harvest microgreens at 7-14 days when true leaves begin to emerge and plants are 1-2 inches tall. Cut just above the soil line with clean, sharp scissors in the morning when plants are fully hydrated. Rinse gently and pat dry. Use immediately or store in refrigerator (unwashed) for up to 5 days in a sealed container with paper towel to absorb excess moisture. Basil and cilantro microgreens are ready at 10-14 days; parsley and dill at 10-12 days; chives at 12-14 days.
Fun Facts
- 🌱 Microgreens can contain up to 40 times more nutrients and antioxidants per gram than their fully mature plant counterparts, making them nutritional powerhouses despite their small size.
- 🌱 Basil microgreens can be harvested in as little as 7 days, making them one of the fastest microgreens to grow, while cilantro and parsley take 12-14 days due to slower germination.
- 🌱 A single standard microgreen tray (10x20 inches) can produce 2-4 ounces of fresh microgreens in 10-14 days with minimal water and no outdoor space, making it one of the most efficient home food production methods.
