How to grow microgreens indoors


Microgreens are not a new type of leafy, green vegetable but a mini version of regular vegetables. Microgreens are simply immature leaves harvested from traditional greens like arugula and cabbage.

You can enjoy the taste of fresh greens in your salad, stir-fry, or stews year-around when you learn how to grow microgreens indoors. Our setup is similar to the unit linked below. Certainly you can start out a lot smaller than what we have installed. 



Indoor Growing Location

A bright location that is away from direct sunlight is needed for growing microgreens indoors. A basement with LED lighting, a south-facing window, or any other bright indoor location that is warm and away from drafts. There are many products readily available at many different price points for beginning your microgreen journey. Click Here for a list of equipment for generating ideas. 


Seed Planting

You will need a shallow container, like a seed tray, for growing microgreens indoors. Use a different container for each seed variety, unless the container is large. Two different types of microgreens can be successfully grown in a large container.

Fill container almost full of potting soil. Level the potting soil but don’t press it down.

Sprinkle your choice of microgreen seeds evenly across the top of the soil. The seeds should be sprinkled thickly with very little space between them.

Sprinkle a thin layer of potting soil on top of seeds. Gently press seeds into potting soil and mist the surface with warm water.

Cover entire tray with plastic wrap to prevent evaporation. Place container of seeds in a warm, bright location away from direct sunlight and drafts.

Daily Check

Check microgreen seeds daily for moisture. If there is visible condensation on the inside of plastic wrap the moisture level is perfect for growing microgreens indoors. If there’s no visible condensation remove plastic wrap and mist soil with warm water, then re-cover with plastic wrap.

Remove plastic wrap when seeds sprout and place microgreens in a sunny location where they will receive 4-hours of direct sunlight every day. If you’re growing microgreens indoors in a basement or other room that can’t provide this much direct sunlight each day, use supplemental LED grow light on microgreens.

Microgreens can be harvested as soon as the second set of leaves appear on plants.

Plant Choices

Arugula, broccoli, cabbage, chickpea, cilantro, kale, leek, lettuce, mint, mung bean, mustard, parsley, radish, rutabaga, turnip, and sorrel and just a few of the plants you can choose from when growing microgreens indoors.
