Microgreens are the baby shoots of edible vegetables and herbs, harvested just after the cotyledons (seed leaves) and the first set of true leaves appear. Though tiny in size, these greens are bursting with flavor, nutrients, and visual appeal. Best of all? They’re incredibly easy and quick to grow indoors—no garden or deep container required.
Microgreens offer an ideal introduction to indoor gardening. Whether you’re short on space or time, these miniature greens can be grown in trays on a countertop, shelf, or sunny windowsill. Most varieties are ready to harvest in just 7-21 days, and they bring vibrant color and punchy taste to sandwiches, salads, and more.
Soil and pH Requirements
Microgreens don’t need a lot of soil, but they do appreciate a healthy, supportive base that allows their roots to grow quickly and evenly.
- pH Range:Aim for a pH between 0 and 6.5, which works well for most varieties.
- Growing Medium:Use a sterile, lightweight seed-starting mix or coconut coir. You can also experiment with hydroponic mats made of hemp, jute, or felt—no soil required!
- Nutrients:Because microgreens are harvested so young, they don’t need heavy fertilization. A rich seed-starting mix usually provides all the nutrition they need.
Light Requirements
Although they don’t need to mature fully, microgreens still require light to develop strong stems and vivid colors.
- Light Needs:Provide at least 10-12 hours of bright light daily. Without it, greens can become leggy and pale.
- Lighting Options:Full-spectrum LED grow lights are perfect and help ensure even, consistent growth. They can be suspended just 4-6 inches above the trays.
- Natural Light:If relying on sunlight, choose a bright windowsill with direct morning or afternoon sun. Rotate trays for uniform growth.
Watering Guidelines
Because microgreens grow quickly and densely, moisture management is key.
- Watering Frequency:Keep the soil evenly moist but not soggy. Most growers water once or twice a day depending on the environment.
- Method:Bottom watering is ideal—place trays in a shallow dish of water and let them soak for 15-30 minutes. This prevents damping-off and keeps leaves dry.
- Drainage:Always use trays with drainage holes if using soil. Good airflow also helps reduce mold risk.
Indoor Growing Environment
Microgreens don’t need fancy conditions—but they do love consistency.
- Temperature Range:A steady 65-75°F (18-24°C) is optimal for most varieties.
- Containers:Use shallow trays or recycled clamshell containers with drainage. No deep pots needed.
- Air Circulation:A small fan on a low setting will keep air moving and reduce the chance of mold.
- Harvesting:Cut microgreens with scissors just above the soil line when they’re about 2-3 inches tall and before the second set of leaves grows in.
