How to Grow Microgreens for a Gourmet Super Green


We'll show you how to grow microgreens further below on this page, but first let's talk about what microgreens are and why they can be another option to traditional jar or vertical sprouting methods.

What are Microgreens?

We generally place microgreens in the same category as super sprouts, but they are not  really "sprouts" in the technical sense.

Sprouts are produced from the same vegetable and herb seeds, but are eaten in the earlier stages of growth just after the baby leaves pop out and turn green. Microgreens begin their life as sprouts, but continue to mature sprouting up to two or more sets of leaves.

Sprouts are easier, faster and less demanding than growing microgreens, but their leaves are much smaller and thus produce less edible chlorophyll. 

Microgreens grow roots and become thick mini hedges that, after a week or so growing time (depending largely on variety), you can snip them off and add to salads.  They also produce more bulk produce for the small amount of seeds you typically use. 

Sprouts grow on moist air while microgreens grow vertically on a soil or hydroponic medium.

Sunflower, buckwheat and pea shoots can be considered microgreens, but technically they shouldn't be sprouted longer than 2 weeks or produce more than their first set of leaves.  They also have larger leaves as compared to other microgreen varieties. 


Most microgreens have small leaves and are more delicate in nature, growing between 1/2" to 3" in height. They have long white sprout stems at the bottom and two sets of leaves. 

Some of you might be familiar with cress, a very common microgreen grown in the U.K. and used on the common English "cucumber sandwich."  This is a good example of using sprouting seeds to grow mini green gardens that produce fresh produce right on your kitchen counter top.

You can also grow some sprout varieties like broccoli, clover, mustard, alfalfa, radish, onion and others as a jar sprout or as a microgreen.


How are Microgreens Used?


Microgreens, or sometimes spelled "micro-greens", are used like sprouts as a garnish, gourmet salad green or to accent a meal or entree.

They are quickly becoming the new gourmet green, described as somewhere between a sprout and a mesclun salad green.   In fact, the term "microgreen" and growing greens in this way is a fairly new concept and first originated in the late 90's. 

The now popular mesclun greens or salad mixes sold in stores across the U.S. actually began in the 1980's.  Microgreens are similar to baby mesclun greens in that you grow the leaf in a short amount of time to produce a tender texture and unique young flavor compared to that of a mature lettuce plant.

How to Grow Microgreens

It is easy to learn how to grow microgreens and blend your own seed mixes that combine a variety of leaf flavors, colors and shapes. There are many options and possibilities to play with, creating your own unique mixture of taste sensation and visual appeal.

(Click here to go to the bottom of this page for a list of options and microgreen varieties.)

Here is are our general "how to grow microgreens" guideline for indoor and/or outdoor tray gardening, depending on the season and growing location.

Things You Will Need:

  1. Containers, trays or sprouters - pint size, half-pint size, long black sprouting trays or commercial sprouters
  2. Soil - preferably high quality organic potting soil, mixed with worm compost (optional)
  3. Seeds - organically grown, non-GMO and non-irradiated
  4. Water - use high quality filtered water or blend of ocean water solution
  5. Sunlight - a half day of direct sunlight outside, through a window or by using artificial full spectrum lighting
  6. Warmth - best grown in warm conditions above 65 degrees F, depending on the variety
  7. Air - good oxygen circulation and air flow
  8. Seaweed Solution (optional) - for super dosing with nutrients especially minerals

The Steps

1) Container, Tray or Sprouter
2) Choosing Your Soil Medium
3) Buying and Spreading the Microgreen Seeds
4) Watering Your Microgreens
5) Sunlight - Direct or Window Sill
6) Warmth and Avoiding Cold Temperatures
7) When to Harvest Microgreens


1) Container, Tray or Sprouter

The first step in learning how to grow microgreens is to find the best container for your needs and budget.  Some of you might want to save any used plastic salad mix containers so you don't have to buy one.  Others might want to purchase one of those  2o" x 1o", thick, black plastic trays, commonly used to grow wheatgrass. They are a bit more heavy duty and can be purchased online or at a nursery or garden store. 

Your tray will also need a dark lid that blocks out the light during the germination process.

Sprouters specifically designed for growing micro-greens are also available.  Some are simple vertical stacks of plastic or clay trays, while others are grown in slide out trays that lay side by side.  (See left hand side column for links to some options.) 

The stackable sprouters are designed to take up less counter space when you initially germinate the seeds with the lid on.  With these sprouters you can start up to five trays at a time, depending on the model.

2) Choosing Your Soil Medium


You can grow your microgreens hydroponically without the use of a soil medium, but for this page we will we only discuss soil grown methods for those new to sprouting. It is less complicated and easier to learn.

We like to grow our micro's on homemade soil compost or high quality organic soil mixed with 10-20% worm compost. Make sure to fill up your trays to the very top of the container or sprouting tray.  As you water, the soil medium will shrink down somewhat so it is good to start out with a full tray.

3) Buying and Spreading the Microgreen Seeds


When you purchase bulk sprouting seeds it is always beneficial to go with a company that sells seed exclusively for growing microgreens or sprouts.  This ensures their viability and quality.  We always recommend using organic, non-GMO and non-irritated seeds that will help to produce healthy vibrant sprouts. 

Learning how to grow microgreens employs a different seed planting technique similar to growing sunflower greens.  This involves taking a few teaspoons worth of seeds and scattering them sparingly some ¼” apart on average over the TOP of your soil medium.

Before spreading your seeds make sure to moisten the soil first and then lightly mist the seeds after you scatter them over the surface.

4) Watering Your Microgreens


As we mentioned, the first watering involves using a spray bottle or mister to mist your soil medium well before you place the seeds on top.  Continue lightly misting daily after the seeds are scattered and until the sprouts fully open their first set of leaves.  At this point you remove the lid and now will be either watering at the level of the soil or, if you have holes in the bottom of the tray, can soak it in a sink or tray of water.

The most important thing to remember when learning how to grow microgreens is to never use overhead watering techniques except with a fine mister, or leave them out in the rain.  This will damage and most likely flatten them and they will have a hard time recovering.

5) Sunlight, Direct or Window Sill

When learning how to grow microgreens that are green and packed with chlorophyll you must expose them to some kind of full spectrum lighting.


It is always best to use direct sunlight when "greening" your microgreens, but this depends on the time of year and amount of sun available. In the summer you can leave them outside 24/7, but for cooler night time temp's you'll want to bring them indoors.  Some micro's can handle more direct sunlight than others so also keep this in mind when placing them in hot sun for more than 2 hours.

The greening process is done after the lid is removed from the sprouting tray. This is what grows your leaves, so the more light the bigger your greens will be at the end.

At this point, you will be growing your greens in as much light as possible throughout the day and watering them everyday.

How to Grow Microgreens Indoors

To grow microgreens indoors you will need to place them near a sunlit window or provide some kind of artificial full spectrum lighting or "grow lights" if you live in a cloudy climate.  You also might want to purchase a lighted 2 or 4 tier shelf growing stand or a compact mini green house stand that are specifically designed for sprouting trays of greens.


Appropriate lighting is an important thing to consider before you commit to starting any microgreen mini-garden.  Many times a kitchen window sill is the perfect place to grow microgreens indoors. 

One of the best things about growing your greens this way is that you can move them around to areas that get more or less light.  This is not something you can do when growing produce in the ground.

We have even traveled with micro-greens sprouting on the dashboard of our vehicle.

Benefits of Growing Microgreens

  • Low start up costs
  • Easy to grow
  • Harvested within 2-3 weeks
  • Provides more produce per teaspoons of seeds
  • High in chlorophyll content
  • Tastes delicious and are full of flavor
  • Many variety options to play with
  • Adds a creative, artsy aspect to gourmet food stylizing

6) Warmth and Avoiding Cold Temperatures

One of the secrets when learning how to grow microgreens successfully is providing them with plenty of warmth. Some micro-greens, like basil, won't even grow in temp's below 75-80 degrees F and other "winter vegetables" like kale or broccoli don't seem to mind cooler temp's.  Most micro's like warmer conditions and respond accordingly by growing at a much faster rate.

For colder temperatures you can buy an electric grow mat that can be placed under the tray for additional heat.  Another option is an enclosed plastic green house that can hold up to four 2o" x 1o" trays of greens.

7) When to Harvest Microgreens


Most microgreens can be harvested after the second leaves emerge and get sizable.  It is always good to taste test to make sure the particular variety you are growing is ready to be picked and eaten.  This is usually pretty obvious visually because you have a full hedge of beautiful greens that are dense and tightly packed.

Some greens are more tall and slender while others have bigger leaves and tend to grow closer to the soil.


To harvest them you need to get out your kitchen scissors and snip a bunch of greens at the base as close as you can to the soil.

You can enjoy them fresh, immediately transferring them over to your salad bowl or they can also be stored in the fridge. We usually keep them in a plastic bag or sealed container of some kind so they will last for several days, just like lettuce or other green leafy vegetables.
