Growing Green Pea Microgreens

Green Peas are one of the more popular microgreens, not only because they’re easy to grow but for their fresh crunchy pea flavor and their beautiful appearance. Growing Green Peas is easy and the method is the same for all pea varieties.

The great thing about peas is that they have super strong roots and you can grow them without medium using just a mesh tray and empty tray for drainage.

Step 1 Measuring & Pre-Soaking Your Pea Seeds

First, you need to measure your seeds using a scale. The best seeding rate for a 10″ × 20″ tray is 200-250 grams. If you plan to grow them in a 10″ × 10″ tray then simply divide the total amount by two, in this case, 100-125 grams.

If you’re a rebel like me you can just eyeball it without weighing, just make sure that your seeds are approx ⅛-¼” (3-6mm) apart.

Pro Tip 1
I recommend you use the shallow 10″x20″ or 10″x10″ trays for easier harvest and better air circulation. This will reduce the chances of fungi developing.

Once you’ve measured out your seeds you should first rinse them under running water in a colander to rinse off any dirt, dust, or contaminants on the seeds.

Next, place them in a container or a large bowl and fill them with water approximately 2 inches above the seeds as they will soak up water during this step, this is called imbibition.

Leave the seeds to soak for 4-8 hours, do not soak them any longer than 12 hours or you risk drowning the seeds. Once they have soaked and expanded in size rinse them under running water one last time and drain thoroughly.

Pro Tip 2
Do not soak your seeds more than once. This will cause them to go soft and rot, ultimately destroying the seeds.

Step 2 Sowing Your Seeds

Fill your tray with your preferred medium, it can be soil, potting mix, coco coir, etc, leaving 1-2cm of empty space from the tray edge to the soil level.

Leaving a small space between the tray edge and grow medium helps when it comes to harvesting, minimizing the chance of digging into the medium with your knife.

Mist your medium with a spray bottle so it’s damp but not saturated and finally spread your seeds evenly across the medium making sure they’re evenly spread out. Lastly, mist your seeds so they’re all covered with a fine mist of water.

Step 3 Germination & Weight Period

Grab an empty tray with no holes and place it on top of your sowed seeds. I use a 15lb (6.80kg) paving block for 10″ × 20″ trays or a 7lb (3.17 kg) brick on 10″ × 10″ trays.

This helps the seed radicle to bury into the medium when it emerges. Without weight, the radicles have a tougher time digging into the growing medium.

Keep in mind that the seeds will germinate while they’re covered and weighed down. A lot of people confuse the germination and weight period to be independent of one another and that you add them together, this is incorrect.

The germination time is there to give you an idea by what time the seeds will germinate, but you don’t add the germination time and blackout period together.

While your seeds are germinating and are weighed down you will need to keep your medium moist. You can do this by lightly misting your seeds every 12 hours, once in the morning and once at night.

Step 4 Blackout Time

After 2-3 days of weight period, the seeds should have germinated and the seedlings should now be lifting the tray with the weight in it. It’s now time to remove the weight and start the blackout period.

Take out the weight from your empty tray and flip it upside down to create a blackout dome and place it back over your seeds.

Keeping them in the dark for 2-3 days will force the freshly sprouted seedlings to stretch and search for light allowing them to get some height.

You can now start bottom watering your microgreens. To do this you simply add water to your bottom drain tray. I personally add 1 cup of water twice a day (every 12 hours), once in the morning and once in the evening.

When the 1-2 days of blackout time have passed you can remove the top tray/blackout dome and introduce your microgreens to light. I’ve found that 17 hours under lights and 7 hours with the lights off work well for me.

Grow your green peas anywhere from 8-16 days, following with daily watering of 2 cups per day, once every 12 hours.

Pro Tip 3
You should be taste testing your green peas daily, starting on day 8 all the way through day 16. This way you can find at which point the microgreens taste best to you.

Step 5 Harvest

Harvesting your pea microgreens is straightforward that only requires a sharp tool. Personally, I absolutely love using the Green Mercer Produce Knife—I highly recommend it! But if you prefer scissors, that’s also completely fine; just make sure they’re sharp!

Now, here’s an important tip to keep your harvest pristine; make sure to keep your chosen tool (whether it’s a knife or scissors) away from the soil! It’s imperative in avoiding any accidental contact between the blade and the soil, you don’t want any unwanted dirt from sneaking into your microgreen harvest and contaminating it.

By following this important pointer, you’ll ensure that your harvested microgreens are of top notch quality and purity.

Plant Details & Taxonomy

Pisum sativum is a small, round seed or seed-pod fruit.

It is an annual plant that completes its life cycle in one year.

The weight of each pea seed ranges between 0.1 and 0.36 grams.

They are a cool-season crop cultivated for their edible seeds or seed pods.

Pea microgreens are known for their robust root systems, which make them ideal for growing in soil.

However, they can also be grown hydroponically or without a medium, provided the appropriate setup is in place.

Microgreen Pests & Diseases

The following are the most common pests and diseases that can affect your microgreens.


White Mold – Sclerotinia sclerotiorum

Sclerotinia sclerotiorum is a necrotrophic fungal disease that causes what’s known as white mold, it can infect over 400 plant species worldwide. It’s also called cottony soft rot, stem rot, watery soft rot, crown rot, and seedling blight.

S. sclerotiorum key properties are its ability to create sclerotia which are its black resting structures, and mycelium which are the white fuzzy spiderweb-like growths you see on stems and growing medium.

microgreens suffering from damping off disease

Damping Off

Damping-off is an umbrella term that covers fungi and fungi-like organisms in several genera including Rhizoctonia, Botrytis, Phytophthora, and Fusarium, with the soil fungus Pythium being the often culprit.

Damping-off is a soil-borne fungal disease that affects seeds and seedlings typically by rotting of the stems and roots at and below the soil surface.

When a seed germinates the seedling will emerge fine but within 24 hours to a few days will become mushy and water-soaked, collapse at the base of the stem and die.

Aphids crawling on a plant stem

Aphids – Aphidoidea

Aphids suck! Quite literally. They’re soft-bodied insects that use their piercing-sucking mouths to feed on plants and there are over 4,000 aphid species in the world.

Other common names are greenflies, blackflies, and plant lice. They come in varying colors such as light green, black, white, brown, gray, or yellow.

When aphids feed on plants they secrete a sticky fluid which is called honeydew (no, don’t eat it). This goo they leave behind drips onto plants and can attract other pests such as ants. If the honeydew is left on leaves it can promote black sooty mold.
