From broccoli and radish to sunflower and pea shoots, these 22 best types of microgreens for indoor growing offer delicious flavors, vibrant colors, and excellent options for beginners and experienced gardeners alike.
1. Broccoli Microgreens
Broccoli Microgreens are among the most popular microgreens for indoor growing because of their quick growth, mild flavor, and nutritional value. These young seedlings feature delicate green leaves and slender stems, making them excellent additions to salads, sandwiches, smoothies, and healthy meals. Their compact growth and simple care requirements make broccoli microgreens ideal for beginners who want to grow fresh, nutritious greens indoors throughout the year.
Identification
- Scientific Name: Brassica oleracea var. italica
- Common Name: Broccoli Microgreens
- Plant Height: Approximately 2–3 inches
- Leaf Color: Bright green
- Stem Color: Pale green to white
- Growth Habit: Dense, upright seedlings
- Harvest Time: Approximately 8–12 days after sowing
Ideal Indoor Growing Conditions
Broccoli microgreens grow best in temperatures between 65°F and 75°F (18°C–24°C).

Harvest with clean scissors just above the growing medium when the cotyledons are fully developed and the seedlings reach the desired height.
22. Lettuce Microgreens
Lettuce Microgreens are delicate, mild-flavored young greens that make an excellent addition to indoor vegetable gardens. Their tender leaves, soft texture, and fresh taste are ideal for salads, sandwiches, wraps, and decorative garnishes. Different lettuce varieties produce attractive green, red, or purple foliage, adding color to indoor growing trays. Although lettuce microgreens may take slightly longer to develop than some brassica varieties, they remain a rewarding choice for gardeners with limited space.
Identification
- Scientific Name: Lactuca sativa
- Common Name: Lettuce Microgreens
- Plant Height: Approximately 1–3 inches
- Leaf Color: Light green, dark green, red, or purple
- Stem Color: Pale green to reddish
- Growth Habit: Compact, delicate, upright seedlings
- Harvest Time: Approximately 10–16 days after sowing
Ideal Indoor Growing Conditions
Lettuce microgreens grow best in cool temperatures between 60°F and 70°F (16°C–21°C). Use shallow trays filled with a fine-textured, well-draining seed-starting mix. Scatter untreated lettuce seeds evenly across the moist surface and cover them only very lightly, since many lettuce varieties germinate best with some light exposure. After germination, provide approximately 12–16 hours of bright LED grow lighting daily. Avoid excessive heat, which can interfere with germination and healthy growth.
Watering and Maintenance
Keep the growing medium evenly moist without allowing standing water around the delicate roots. Mist gently during germination and switch to careful bottom watering once the seedlings develop. Maintain adequate airflow and avoid overcrowding to reduce mold and damping-off problems. Fertilizer is generally unnecessary during the short growing period. Harvest lettuce microgreens with clean scissors just above the growing medium when their cotyledon leaves are fully expanded or the first true leaves begin appearing.
FAQs
1. What Are the Best Microgreens to Grow Indoors?
Broccoli, radish, sunflower, pea shoots, and kale are among the best microgreens for indoor growing. They germinate relatively quickly, require minimal space, and grow well in shallow trays. These varieties are excellent for beginners and provide fresh, flavorful greens throughout the year.
2. How Long Do Microgreens Take to Grow Indoors?
Most microgreens take approximately 7–21 days to reach harvestable size, depending on the variety and growing conditions. Radish and broccoli grow quickly, while cilantro and spinach generally take longer. Proper lighting, consistent moisture, and suitable temperatures help encourage healthy development.
3. Do Microgreens Need Sunlight to Grow Indoors?
Microgreens need adequate light after germination to develop healthy leaves and strong stems. A bright windowsill may work, but LED grow lights provide more consistent results. Most varieties benefit from approximately 12–16 hours of supplemental lighting daily, followed by a dark period.
4. Can You Grow Microgreens Indoors Without Soil?
Yes, many microgreens can grow without soil using coconut coir, hemp mats, or other suitable growing media. Some varieties also grow in hydroponic systems. Maintaining consistent moisture, proper lighting, and good airflow is essential for producing healthy microgreens without traditional potting soil.
5. How Often Should You Water Microgreens Indoors?
Check microgreens daily and water whenever the growing medium begins to dry. The medium should remain moist but never waterlogged. Bottom watering is often recommended after germination because it reduces excessive moisture on delicate stems and leaves, helping prevent fungal problems.
