Microgreen Varieties That Grow in 7 Days on a Sunny Balcony
Microgreens are the ultimate fast crop: compact, nutrient-dense, and ready in under a week. With just a sunny balcony, shallow trays, and a handful of seeds, you can harvest fresh greens in days — no backyard required.
Why Microgreens Belong on Your Balcony
Microgreens are harvested at the seedling stage, usually 7–10 days after germination. At this point, they’re packed with concentrated vitamins, minerals, and phytonutrients. For urban dwellers, they offer a way to grow food without soil beds or large containers. A sunny balcony provides enough light, airflow, and space to sustain multiple trays of microgreens, making them one of the most accessible crops for apartment living.
🌱 Radish Microgreens
Radish microgreens are among the fastest to germinate, often sprouting within 24–48 hours and ready for harvest in 5–7 days. Their flavor is sharp and peppery, adding zest to salads, sandwiches, and stir-fries. Radish varieties like Daikon or Red Arrow produce vibrant stems that also add visual appeal to dishes.
🌱 Arugula Microgreens
Arugula microgreens deliver a bold, peppery taste and are ready in 6–7 days. They thrive in shallow trays and require consistent moisture. Arugula pairs beautifully with pasta, pizza, and fresh salads, offering a gourmet touch from a balcony harvest.
🌱 Mustard Microgreens
Mustard greens sprout quickly, often within 6 days, and produce tangy, spicy leaves. They’re resilient, forgiving of minor watering mistakes, and add a distinctive kick to wraps, soups, and Asian-inspired dishes. Yellow and red mustard varieties also bring color diversity to your microgreen mix.
🌱 Broccoli Microgreens
Broccoli microgreens are mild in flavor but exceptionally nutrient-dense, containing sulforaphane and antioxidants linked to health benefits. They’re ready in about 7 days and are versatile enough to blend into smoothies, sprinkle over grain bowls, or mix into omelets.

Balcony Growing Setup
To succeed with microgreens, you don’t need expensive equipment. A few shallow trays, a spray bottle, and a bag of potting mix or coconut coir are enough. Place trays where they’ll receive 4–6 hours of direct sun. Rotate them daily to ensure even growth. Mist lightly twice a day to keep seeds moist but not waterlogged. Within a week, you’ll have a lush carpet of greens ready to harvest.
Harvesting & Using Microgreens
Harvest microgreens when they reach 2–3 inches tall. Use clean scissors to snip just above the soil line. Rinse gently and pat dry. Microgreens are best eaten fresh but can be stored in the fridge for 3–4 days in a sealed container. Add them to salads, sandwiches, smoothies, or as garnishes for soups and entrees. Their concentrated flavor and nutrition make them a powerful addition to everyday meals.
Tips for Success
- Scatter seeds evenly to avoid overcrowding.
- Maintain consistent moisture with misting, not heavy watering.
- Ensure trays have drainage holes to prevent mold.
- Harvest promptly at 7 days for peak flavor and nutrition.
