What are Microgreens?

Microgreens are young, edible greens that are harvested at the cotyledon or first true leaf stage of growth. 

They are typically harvested when they are just a few inches tall, making them smaller than baby greens but larger than sprouts. 

Despite their small size, they are packed with flavor and nutrients, including vitamins, minerals, and antioxidants.

  • Look for seeds that are organic, non-GMO, and untreated with chemicals or pesticides. 
  • Quality seeds will produce healthy, flavorful sprouts with optimal nutrition.


  • Consider how much you plan to grow and order seeds accordingly. 
  • Most microgreen seeds are sold in packets or bulk quantities, depending on your needs. 
  • Keep in mind that these types of sprouts are typically grown densely, so you’ll need more seeds than you would for traditional garden crops.

Seed Supplier 

  • Choose a reliable seed supplier with a good reputation for quality and customer service.
  • Look for suppliers that specialize in microgreen seeds and offer a wide selection of varieties to choose from. 

Some popular seed suppliers include Johnny’s Selected Seeds, True Leaf Market, and Baker Creek Heirloom Seeds.

  • Check the germination rate of the seeds before ordering. 

Higher germination rates indicate seeds that are more likely to sprout quickly and uniformly, leading to a higher yield.

Storage and Shelf Life 

  • Consider the storage requirements and shelf life of the seeds. 

Most microgreen seeds have a long shelf life when stored properly in a cool, dry place away from direct sunlight. 

However, it’s a good idea to check the expiration date on the seed packet and use fresh seeds whenever possible for optimal germination and growth.

Variety Packs 

  • Consider purchasing variety packs or sampler packs that contain a selection of different seeds. 

This allows you to experiment with different flavors, colors, and textures in your microgreen garden and discover new favorites.

By considering these factors and choosing the right seeds, you can enjoy a bountiful harvest of fresh, flavorful greens to enhance your meals and elevate your culinary creations.

Choose Growing Containers 

  • You can grow microgreens in shallow trays, plastic containers, or even repurposed egg cartons. 
  • Make sure the containers have drainage holes to prevent waterlogged soil.

You can usually pick up trays for free at Home Depot and Lowes in their Gardening Department.

Prepare Growing Medium 

Choosing a suitable growing medium that supports the roots, retains moisture, and promotes healthy growth is important. 

Here are some common options for growing mediums:

Potting Mix

  • A high-quality potting mix or seed-starting mix is a popular choice for growing microgreens. 
  • These mixes are lightweight, well-draining, and sterile, making them ideal for germinating seeds and supporting young seedlings. 

Look for mixes specifically formulated for starting seeds, as they typically contain a balanced blend of organic matter, perlite, and vermiculite.

Coconut Coir 

  • Coconut coir, also known as coco coir, is a natural fiber derived from coconut husks. 
  • It is an eco-friendly and sustainable alternative to peat moss and has excellent water retention properties. 

It is available in compressed bricks or loose fibers and can be mixed with perlite or vermiculite to improve drainage. I use these bricks from Amazon.

Hydroponic Mats 

  • Hydroponic mats or grow pads are specially designed for hydroponic growing systems and provide an inert, soil-free medium. 

These mats are made from materials such as felt or fleece and absorb water to keep seeds moist during germination. I use these mats in my trays.

Hydroponic mats are reusable and can be easily cut to fit different tray sizes.

Cover and Water 

  • Cover the seeds with a thin layer of soil or vermiculite to help retain moisture. 
  • Water the soil gently using a spray bottle or watering can with a fine mist setting.

Provide Adequate Lighting for your Microgreens

Adequate lighting is crucial for growing healthy and vibrant microgreens indoors. 

Since microgreens are typically grown in trays or containers indoors, providing the right amount and type of light is essential for promoting strong growth and development.

Here are some considerations for lighting:

Natural Light 

Ideally, microgreens should be placed in a location with access to natural sunlight. 

A bright, south-facing windowsill is often the best spot for growing microgreens, as it provides ample sunlight throughout the day. 

However, it’s important to avoid direct sunlight during the hottest part of the day, as this can cause them to wilt or scorch.

Supplemental Lighting 

In cases where natural light is limited or inconsistent, supplemental lighting may be necessary to ensure optimal growth.

LED grow lights are an excellent choice for providing supplemental lighting. 

LED lights are energy-efficient, produce little heat, and can be customized to provide the specific spectrum of light needed for plant growth. 

Position the grow lights directly above the microgreens, keeping them 6-12 inches away from the tops of the plants.

Light Spectrum 

Microgreens require a full spectrum of light for healthy growth, including both blue and red wavelengths. 

Blue light promotes vegetative growth and compact, sturdy stems, while red light stimulates flowering and fruiting. 

LED grow lights designed specifically for plant growth often provide a balanced spectrum of light that mimics natural sunlight, promoting robust growth and vibrant colors in microgreens.

I ordered a 2 pack of LED Spectrum Grow Lights from Amazon. These work very well and have a super long life!

Light Duration

Microgreens typically require 12-16 hours of light per day to grow optimally. 

Use a timer to ensure consistent light exposure, turning the grow lights on in the morning and off in the evening to mimic a natural day-night cycle. 

Consistent light exposure is essential for promoting healthy photosynthesis and preventing leggy or weak growth.

Light Intensity 

The intensity of light is also important for microgreen growth. 

Aim for a light intensity of 200-400 micromoles per square meter per second (µmol/m²/s) for optimal growth. 

You can measure light intensity using a light meter or by referring to the manufacturer’s specifications for your grow lights.

By providing adequate and consistent lighting, you can ensure healthy growth and development of your microgreens, resulting in vibrant colors, robust flavors, and nutritious harvests. 

Experiment with different lighting setups and durations to find the optimal conditions for your microgreen growing environment.

Monitor and Water Regularly 

Keep the soil consistently moist but not waterlogged. 

Check the moisture level daily and water as needed to prevent drying out.

Watch for Growth 

Within a few days to a week, you should start to see tiny sprouts emerging from the soil. 

Continue to monitor the growth of your microgreens, ensuring they receive adequate light and water.

Harvesting Microgreens

Microgreens are typically ready to harvest when they have developed their first true leaves, which usually occurs within 1-3 weeks after planting, depending on the variety. 

To harvest microgreens:

Use Scissors 

  • Using sharp scissors or a clean knife, cut the microgreens just above the soil level, leaving the roots behind. 
  • Avoid pulling the greens out of the soil, as this can disturb the roots of neighboring plants.
