Pak Choi is a member of the cabbage family, and it has its origin in China. You may have heard of it as Bok Choi, Pak Choir, or Choi Sum. Well, all of them are the same plant! It’s also referred to as the Chinese cabbage. 

The full-grown vegetable has a white and thick stem (shaped like a bulb) and green leave blades (similar to celery-like stalks). All parts of the Pak Choi are edible, the same as the microgreen.

How to grow Pak Choi Microgreens 

Pak Choi is a fast-growing microgreen and easy to manage. It makes them ideal for beginners growing at home.

To grow Pak Choi microgreens at home, you need a few materials to get you started: 

You can grow them in potting soil, coconut coir, or using a hydroponic mat. Either way will work well. 

When growing microgreens, it’s beneficial to use a container with drainage holes and a bottom tray with none. You then place the top one in the bottom one, and it catches any excess water.

Find the container of your choice and fill it up with your growing medium. Always flatten it out to make an even surface. It will help you when you sprinkle the seeds, and you will get a uniform distribution. 

Some seed types benefit from being soaked in advance, but with Pak Choi, you can skip this step. You don’t have to presoak the seeds, but you plant them directly. 

Once you have planted the seeds, place the container in the dark to support the germination (this is referred to as the Blackout period). When you deprive the seeds of light, you help them germinate as you are mimicking the same process as if the seeds were planted and dug down in the soil.  

You can use a piece of aluminum foil, another tray, a towel, or similar to cover your container for around three days. Once the seeds have developed into about an inch to an inch and half long stems, you know they are ready to be exposed to the light. 

Place your tray in a window sill where there is enough light coming through (minimum of 6 hours a day) or under a grow light. Leave the microgreens for another five days until they have reached their mature stage. It’s when they have grown bright white stems and have developed their first true leaves. Pak Choi leaves are small with rounded corners.

During both the blackout period and sunlight period, you should gently water your microgreens twice a day; once in the morning and once in the evening. It’s important that you keep the soil moist, but never soaked. 

Overwatering is one of the most common mistakes and what causes crops to grow mold. So always keep an eye on your container to ensure that you give the right amount of water and good airflow.
