They allow the plant to take up nutrients from the soil more efficiently than other types of plants grown from broccoli seeds. It is crucial to harvest broccoli at the right time to ensure maximum nutrient absorption.

Cons to Consider

While broccoli microgreens offer many health benefits, such as sulforaphane, there are some cons to consider as well. One potential issue is nitric oxide buildup.

Nitric oxide is a gas that can build up in closed environments with high humidity levels. If you’re growing your own broccoli microgreens, it’s important to ensure that the growing environment is well-ventilated to prevent nitric oxide buildup, as broccoli is known for its high levels of sulforaphane.

Another potential issue is sulforaphane. Because broccoli microgreens are harvested so early in their growth cycle, they can contain lower levels of sulforaphane than mature broccoli plants. It’s important to store them properly and use them quickly after harvesting to ensure maximum sulforaphane content. Additionally, sulforaphane can be destroyed by heat, so it’s best to consume broccoli microgreens raw or lightly cooked.

Growing Broccoli Microgreens at Home: Step-by-Step Guide

If you’re looking for a quick and easy way to add some nutrition to your diet, growing broccoli microgreens at home is an excellent option. These tiny greens are packed with sulforaphane, vitamins, and minerals, making them a healthy addition to any meal. In this step-by-step guide, we’ll show you how to grow broccoli microgreens in just a few days.


  1. Start by soaking your broccoli sprouts in water for 12 hours. This will help them germinate more quickly.
  2. After soaking, drain the water and rinse the broccoli sprouts thoroughly.
  3. Take a shallow container with drainage holes and fill it with soil up to 1-2 inches depth. Sprinkle broccoli seeds on top of the soil and water gently to encourage the growth of broccoli sprouts.
  4. Evenly distribute the soaked broccoli sprouts seeds over the soil surface using a shaker bottle or your fingers if you don’t have one.
  5. Sprinkle some more soil on top of the seeds so that they are covered lightly and then press gently down.
  6. Water gently until moist but not too wet as this can lead to mold growth.
  7. Cover the container with another tray or lid that allows air circulation but doesn’t let light through completely.
  8. Place it in a bright area without direct sunlight for 2-3 days while keeping it moist daily by spraying water from above or bottom watering method.

After two days, remove the cover so that they get access to light which helps them produce chlorophyll and turn green.

  1. Keep watering twice daily until they reach around 2 inches height (3-4 days).
  2. Once they reach their desired height, cut them off just above the soil line using scissors or knife.

Using a shaker bottle is helpful

Using a shaker bottle is an effective way to evenly distribute seeds on top of the soil without overcrowding certain areas leading to uneven growth patterns.

It also prevents mold growth by allowing air circulation and reducing the chances of water pooling in one area.

In just a few days, you can have fresh and nutritious broccoli microgreens with strong roots

According to a study, broccoli microgreens contain up to 40 times more nutrients than mature broccoli. They are rich in vitamins A, C, and K, minerals such as calcium, iron, and potassium.

Growing them at home is an easy way to add some nutrition to your diet without having to go out and buy expensive supplements or spend time searching for them in grocery stores.

How to Sow Broccoli Microgreen Seeds: Amount and Timing

Growing broccoli microgreens is a great way to add flavor, texture, and nutrition to your meals. These tiny greens are packed with vitamins and minerals, making them an excellent addition to salads, sandwiches, or smoothies. If you’re looking to grow your own broccoli microgreens at home, here’s how you can sow the seeds for optimal growth.

Seed Density

The first thing you need to consider when sowing broccoli microgreen seeds is the seed density. It’s recommended that you use a seed density of 1-2 oz per 10×20 inch tray for broccoli microgreens. This amount will give you a good yield without overcrowding the tray.

Sowing Method

Once you have your seeds ready, it’s time to sow them. The best way to do this is by using the “topping” method. Simply spread the seeds evenly on top of soil in your tray and cover them with a thin layer of vermiculite or coconut coir. This covering helps keep moisture in while allowing air flow for germination.


Broccoli microgreen seeds can be sown year-round indoors or outdoors depending on the climate conditions in your area. However, optimal growth occurs in cooler temperatures between 60-70°F (15-21°C). Therefore, it’s best to plant them during spring or fall when temperatures are lower.

Germination Process

After sowing your seeds, it’s essential to keep them moist throughout the germination process. Watering from below using a tray filled with water is ideal as it prevents disturbing the delicate roots formed during germination.

It takes about three days for broccoli microgreen seeds to germinate under ideal conditions such as consistent moisture and temperature control between 60-70°F (15-21°C). Once they start sprouting leaves after about five days from germination, you can move them to a well-lit area and continue to water them from below.


Broccoli microgreens are ready for harvest after 10-14 days from sowing. They should be about 1-2 inches tall with two leaves. Use scissors to cut the greens just above the soil line, leaving the roots intact.

Tips for Success

Here are some additional tips that can help you succeed in growing broccoli microgreens:

  • Use high-quality seeds specifically meant for microgreens.
  • Make sure your tray has drainage holes to prevent waterlogging.
  • Keep your tray covered during the first few days of germination to retain moisture.
  • Provide adequate light once the seeds start sprouting leaves by placing them near a sunny window or using grow lights.
  • Avoid overwatering as it can lead to mold growth and root rot.

Preparing the Soil for Broccoli Microgreens: Tips and Tricks

Use a Planting Tray with Drainage Holes to Plant Broccoli Microgreen Seeds

Using a planting tray with drainage holes is essential. This allows excess water to drain out of the tray, preventing the seeds from becoming waterlogged and rotting.

Start by filling the tray with seed soil, leaving about half an inch of space at the top. Then, sprinkle the broccoli microgreen seeds over the soil surface, making sure they are evenly distributed. Cover them with a thin layer of soil and gently press down.

Prepare the Soil Surface by Adding Moist Coconut Coir or Paper Towel before Planting

Before planting your broccoli microgreen seeds, it’s important to prepare the soil surface properly. One way to do this is by adding moist coconut coir or paper towel on top of the seed soil.

Coconut coir is an excellent choice because it has high water retention properties and provides good airflow for germination. Simply soak it in water until fully hydrated, then spread it over the seed soil and press down lightly.

Alternatively, you can use a damp paper towel instead of coconut coir. Wet it thoroughly and place it on top of the seed soil before sprinkling your broccoli microgreen seeds over it.

Water the Tray Using a Spray Bottle and Make Sure There Is Enough Moisture for Germination

After planting your broccoli microgreen seeds, water them gently using a spray bottle. Be careful not to overwater them as this can cause damping off disease.

Damping off disease is caused by fungi that thrive in overly wet conditions and can kill young plants quickly. To prevent this from happening, make sure there is enough moisture in the tray for germination but avoid saturating the soil completely.

Once True Leaves Form, Move The Trays To An Area With Enough Light For Growth

Broccoli microgreens need plenty of light to grow. Once the true leaves start to form, move the trays to an area with enough natural or artificial light for growth.

A sunny windowsill is a great option, but if you don’t have access to one, you can use grow lights instead. Position them about six inches above the trays and keep them on for 12-16 hours a day.

To Promote Air Circulation, Place a Second Tray on Top of The First One After Germination

Air circulation is crucial for healthy broccoli microgreens. To promote it, place a second tray on top of the first one after germination.

This creates a mini greenhouse effect that allows air to circulate while keeping the moisture in. Make sure there is enough space between the two trays so that your broccoli microgreens have room to grow.

Harvesting and Storing Broccoli Microgreens: Best Practices

When to Harvest Broccoli Microgreens

Broccoli microgreens are ready for harvest when they reach around 2 inches in height. This usually takes about 7-10 days after planting. It’s important not to wait too long to harvest, as the greens will become tougher and lose their flavor.

How to Harvest Broccoli Microgreens

When harvesting broccoli microgreens, use a clean pair of scissors or a sharp knife. Cut the stems just above the soil level, being careful not to damage any nearby plants. If you’re growing your microgreens in a tray, you can also gently pull them out by the roots.

It’s best to harvest broccoli microgreens regularly rather than all at once. This promotes continuous growth and ensures that you have fresh greens available whenever you need them.

Storing Broccoli Microgreens

After harvesting your broccoli microgreens, it’s important to store them properly to maintain their freshness and flavor. Place them in a sealed container or plastic bag and store them in the refrigerator for up to a week.

If you have excess broccoli microgreens that you won’t be able to use within a week, consider freezing them for later use. Simply place the greens in an airtight container or freezer bag and freeze until needed.

Growing Broccoli Microgreens at Home

Broccoli microgreens are easy to grow at home with minimal equipment and space requirements. To get started, simply purchase some broccoli seeds from your local garden center or online retailer.

You can grow your broccoli microgreens in trays, pots, or even on paper towels. Fill your chosen container with potting soil or another growing medium and sprinkle the seeds evenly over the surface. Cover lightly with soil and mist with water.

Place your container in a sunny location or under grow lights if you don’t have access to natural sunlight. Water regularly but be careful not to overwater, as this can cause mold or other issues.

Purchasing Broccoli Microgreens from Grocery Stores

If you don’t have the time or space to grow your own broccoli microgreens, you can purchase them from many grocery stores and health food stores. Look for fresh greens that are brightly colored and free of wilting or discoloration.

When purchasing pre-packaged broccoli microgreens, be sure to check the expiration date and store them properly once you get home. If possible, choose a brand that uses sustainable growing practices and organic seeds.
