Now that you have all the equipment in place, let’s start growing swiss chard microgreens.

Step 1: Sow the Seeds (Day 1)

Take 25 grams of swiss chard microgreen seeds into a container.

Now, start preparing your growing trays. Take three trays – one with draining holes and two with no holes.

We will plant the seeds in the tray with draining holes. This way, we can keep a growing tray beneath it, and bottom-water our microgreens. 

Spread soil on the growing tray. Do not fill up to the brim. 

Start spreading the seeds evenly on your growing tray.

Add a layer of coco coir over the seeds. This will help the seeds in germination, and remove the seed hulls easily.

The light pressure of the coco coir also forces the seeds to grow deeper roots and absorb optimum water/nutrition from the bottom tray.

Once you add the coco coir layer, even out the surface to enable proper growth of the leaves.

Step 2: Watering the Seeds (Day 1)

When you water the swiss chard microgreens tray for the first time you need to water it heavily – but not heavy enough that water starts drizzling from the draining holes.

Use the water hose nozzle with low settings and water the seeds evenly.

This way, the soil is loosened creating more air pockets in the soil and allowing healthy growth of the roots.

🔔 Note: Soaking seeds is optional. If you want to soak swiss chard seeds, then do it for 24 to 48 hours before sowing them. 

Once done watering, cover the growing tray with another tray and keep a light weight on the uppermost tray.

This way, the seeds will be pressed deep down into the soil and the hulls will easily be removed once the leaves start to sprout.

Step 3: Watering and Checking (Day 2 to Day 4)

From the next day onwards, you need to water the swiss chard microgreens lightly from ABOVE with the nozzle.

Make sure the settings are low so you don’t flood the growing tray.

After Day 3, you will start to see small sprouts. Water the upper surface lightly and this time cover the growing tray with the upper tray – BUT WITHOUT THE WEIGHT.

Otherwise, the microgreens will be bent or grow wriggly. We want them to grow as straight as possible. So, no weight after day 3.

By Day 4, you will start seeing the roots emerging from the draining holes. Lift the growing tray and bottom-water the swiss chard microgreens. Just a little, don’t over water.

Mist the upper layer of soil with some water.

Step 4: Blackout Period (Day 5)

Now, turn the upper tray upside down and cover the growing tray like this.

This is called the Blackout period.

A blackout period essentially means keeping the seeds away from sunlight. This allows healthy germination and root growth.

Step 5: Watering and Keeping Under the Light (Day 6 to Day 12)

On Day 6, you can start keeping your microgreens under direct light. If you live in a country with sunny weather, you can grow these microgreens under direct sunlight as well. 

4 to 6 hours of daily sunlight is enough.

However, if you are growing microgreens indoors with a light setup, we have a comprehensive guide for you that will tell you which is the best light for microgreens.

Anything under 4000k is a good light source for swiss chard microgreens.

Now, you do not need to cover the growing tray. Just keep the tray under the light and keep checking for water every day. 

Every day, bottom-water the swiss chard microgreens with ½ cup of ocean water solution.

By Day 11 or 12, you will be able to see a healthy batch of swiss chard microgreens sprouting from the tray.

Step 6: Harvest and Store (Day 13)

On Day 13, you will be ready to harvest your swiss chard microgreens. 

Take a sharp knife or a scissor and start cutting the microgreens. BE CAREFUL in this step.

Ensure you do not cut your swiss chard near the soil or you will get soil particles in your bowl of harvest. Just lightly hold a bunch of microgreens from the top and chop at the growing tray’s height.

This will give you a combination of contrasting red stems and green leaves.

How to Store Swiss Chard Microgreens?

To store swiss chard microgreens – or any microgreens for that matter – lock them in an air-tight container or a Ziploc bag.

Microgreens just like any other fruits or vegetables have the highest nutrition and health benefits when they are fresh.

So, it is recommended that you eat them fresh. Wash them a little under the tap water to wash off the soil particles and throw them onto your dish.

However, if you have grown a large batch and want to store some for later. Keep a few things in mind:
